Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a compatible polymer mixture (polymer blend) K consisting of alkyl-substituted polystyrene as polymer acid component P1 and a polymer component P2 having carbonyl groups.

BACKGROUND OF THE INVENTION It is generally assumed that different types of polymers are not compatible with each other, that is, different types of polymers have a general content of less than a small amount of components.

No homogeneous phase results, which would indicate complete miscibility of the components.

Exceptions to this principle are of increasing interest, especially among professionals engaged in theoretical explanations of phenomena. A sufficiently compatible polymer mixture exhibits sufficient solubility (miscibility) at all mixing ratios.

A comprehensive discussion of miscible polymer systems can be found, for example, in R. Faul et al.

To demonstrate this miscibility, the glass temperature Tg

The appearance of LO8T is due to the fact that upon heating, the previously transparent homogeneous polymeric material separates into phases and becomes optically translucent to opaque. This behavior, according to the literature, is clear proof that the original polymer mixture consisted of one homogeneous phase in equilibrium. Other characterizations of the mixture are given by D.

Even very low molecular weight polystyrene is only slightly compatible with PMMA. Therefore, even mixtures consisting of 20% of very low molecular weight styrene oligomers (1t3100 molecules) no longer give a transparent product. Similarly, even at a still very low molecular weight of I/c9600, P

Similarly, other polymethacrylates and polyacrylates can hardly be mixed with polystyrene to form transparent plastics. This includes, for example, polyethyl methacrylate, polybutyl methacrylate, polyimbutyl methacrylate, polyneopentyl methacrylate,
This also applies to polyhexyl methacrylate and many others. R, H, Somani and M, T, Shaw, Macromolecules Volume 14,

An exception to this commonly observed incompatibility between poly(meth)acrylates and polystyrene is reported in two new patent applications (West German Patent No. 363,237).
0.5 and Patent No. 36323+59, specification of R, still unpublished). According to it, polystyrene or poly-α-methylstyrene is very well compatible with polycyclohexyl methacrylate and polycyclohexyl acrylate. In this case, since the compatibility of polycyclohexyl (meth)acrylate with polystyrene and poly-α-methylstyrene is very good, the compatibility between the styrene-containing polymer and the cyclohexyl (meth)acrylate-containing polymer is very good. Solubility still occurs even if the copentapolymer contains much less cyclohexyl (meth)acrylate than 50 f7o (for example 3oon%). Similarly, styrene can be substituted by other copolymers without loss of compatibility between the styrene-containing polymer and the cyclohexyl (meth)acrylate-containing polymer.

In addition to this very complete miscibility of cyclohexyl (meth)acrylate with polystyrene and polyα-methylstyrene, the miscibility of polystyrene with polyvinyl methyl ether, polyphenylene oxide and tetramethylbisphenol-A-i IJ carbonate CD, R, ball (Paul

Miscibility is generally explained by the specific interaction between different types of λ coalescence. i.e. a mixture of compatible polymers as described above (e.g. tetramethylbisphenol-hydrogen-
polycarbonate/polystyrene) is described in terms of electron/donor/acceptor/complexation. (J, W, Parrou, R, Ball, Annu, Rev, Mate
r, Elci, 1981.299-619).

However, most of the hitherto known compatible electroalloy mixtures are due to special interactions of the hydrogen bridge type. (e.g. phenoxy/polyester, pvc/de 13 ester, BAA/f: IJ ester, P O/P

The above-mentioned compatible polymeric polymers may therefore be due to hydrogen bridge bonding or electron/donor/acceptor/complex formation, but may also result from special copolymers of PMMA and styrene and acrylonitrile or α-methylstyrene and acrylonitrile. Soluble (
(found only for a constant styrene/acrylonitrile ratio or α-methylstyrene/acrylonitrile ratio, respectively) is explained by the intramolecular repulsion inside the co-polymerization between the two comonomers styrene and acrylonitrile. It is also buried that compatibility (for example between PMMA and SAN) is found only for very specific compositions of the copolymers. Since compatibility is found only at very specific comonomer ratios, [miscible Fenster (M

Jl, Vol. 18, 521-527 (1986)) describes the miscibility of poly(acrylonitrile-looneystyrene) toboli(acrylonitrile-codetadiene).

Therefore, on the one hand, the compatibility of a particular copolymer with other polymers can be explained by intramolecular repulsion within a copolymer, as mentioned above, and also by the "miscible Fenster" phenomenon found; To account for the compatibility of homopolymers, special interactions (e.g. EDA-complex in the case of polyphenylene oxide/polystyrene or PVDF/P
Hydrogen pole bond of MMA yarn) is cited. There is therefore no complete theory of polymer miscibility that would allow the discovery of new compatible polymeric compositions. However, this lance-compatible polymer composition is sought after in many applications.

Thus, mixtures of polymers (polyprene V) lead to plastic products with improved properties in certain cases and in certain fields of plastics [Kirkuos V-(
Kirk-othmer), 3rd edition, Volume 18, 44
3~478 Sada, J, Riley (vixay) 19
See B2]. The physical properties of such "polyblends" generally represent compromises that represent improvements to the properties of each individual polymer. Multiphasic polymeric polymers are of much greater commercial significance than compatible mixtures (see above, page 449 of Kirkoosmer).

Multiphasic and miscible polymer mixtures should therefore be strictly distinguished both with respect to their physical properties and also with respect to the properties essential to their use, especially their optical properties (transparency, clearness, etc.). As already mentioned, poor compatibility often severely limits the mixing of plastics with the aim of improving the overall property spectrum. However, the prior art has not yet provided a method for finding the compatible iris composite gold that is desired in industry.

Using the knowledge that i) is not necessary at all to understand the miscibility of these polymers.

Rather, the concept of repulsion between copolymer constituents (for example, the repulsion between styrene and acrylonitrile in BAN), which was established to explain the compatibility of copolymers, can be applied to homopolymers. It turns out that it is possible to derive industrial regulations from it. Accordingly, a new theory for understanding polymer mixtures provides: 1) x coalescence P
1 consists of monomeric constituents having at least two mutually repelling chemically distinct sub-positions, and 2) the polymer P2 also comprises at least two mutually repelling monomer constituents 3) a negative or only slightly positive component for mixing polymer 2 with the hydrogenated component of the IL polymer; The miscibility between the different class a polymers P1 and 22 is foreseen if the mixing endlow is determined.

A plausible theory, which clearly explains the miscibility between halogen-containing polymers on the one hand and carzanyl group-containing polymers on the other hand, is demonstrated below. The data required for this purpose can be obtained from general charting work, such as Landolt-B'ornstein, 5th and 6th editions (Ber: Lin, Julins).

This mixture is highly endothermic; i.e. the ΔHm of an equimolar mixture is +5 Q Q cal per mole of mixture.
It is.

Corresponding mixtures of verfluorocyclohexane and cyclohexane are likewise highly endothermic (see FIG. 2). As evidenced by other examples, mixtures of alkanes and perfluoroalkanes are generally endothermic.

Therefore, in PVDP, two repulsive subgroups (OH2 group and OR2 group) are combined in one monomer constituent.

Similarly, 1c m'MMA is composed of two repelling subgroups, a hydrocarbon group and an ester group.

Figure 6 shows the heat of mixing of acetic acid ethyl ester and decalin (288 cal per mole of the mixture), and Figure 4 shows the heat of mixing of pentanone (3) and n-hebutane. A significant h-repulsion is seen between the group and the alkane. Figure 5 shows the repulsion between the aliphatic (cyclohexane) and carbonyl group as a change in temperature during mixing. As is clear, the repulsion is The compatibility of FVDP with PMMA increases as the content of carbonyl groups in PVDF increases.A correspondingly significant cooling occurs during mixing.The compatibility of FVDP with PMMA therefore increases with
, - and CF2- subunits and as a direct result of the repulsion between the aliphatic portion of PMMA and the ester groups. The compatibility of tic pva and PMMA can be explained in exactly the same way. Thus, for example, a mixture of chloroform and cyclohexane is also endothermic (165 cal/l of mixture in a 1:1 mixture). In contrast, the polymer mixture PVC/PMMA corresponds to the mixture 1,1゜21 2-7-) lachloroethane/acetic acid ethyl ester (mixture in a 1:1 mixture, 1 mol Todoro-608Cab
) is highly exothermic. Similarly, the mixture chloroform/acetone is also exothermic, as shown in FIG. A new explanation of the miscibility of PVDF/PMMA and chlorine-containing hydrocarbons/PMMA is provided by the introduction of superior compatible polymers that could not be explained by the rules and standards of the prior art, much less could have been foreseen. This is a direct result of an unexpected discovery.

The new class of compatible polymers according to the invention includes mixtures of two polymers whose compatibility cannot be explained neither by hydrogen bridges nor by EDA-complex formation.

It is caused by repulsion within the monomeric constituents of polymer P1 and within the monomeric constituents of polymer P2, as described in the example of PVDF'/PMMA or PVO/PMMA.

Based on the repulsion between aliphatics and aromatic hydrocarbons. In FIG. 7, the heat of mixing of n-hexane and benzene is described as an example. In this case, it is very common in principle that the compatibility of the I/c1i combination P1 and the polymer P2 occurs when the repulsive forces within the monomer constituents are large by %. Therefore, in particular if the phenylene group in the monomer constituents of the polymer P1 and the aliphatic content present in the main chain directly adjacent to the polar group X in the monomer constituents are as large as possible, Good miscibility between the two occurs.

Preference is given to polymers P1 in which the content of polymers of the formula I is at least 95% by weight. If R1-B, the expression is homo/IJ consisting of the formula 117) lLjt body.
Mer P1 is a very particularly advantageous embodiment.

Comonomers for constituting the polymer P1, if they are generally present, include in particular vinyl phosphomers (different from I).

(see wargenb+srg) 1963]. Preference is given here to monomers consisting exclusively of the elements carbon, hydrogen and oxygen. In particular, these are vinyl esters and/or (meth)acrylic esters, which generally have 4 to 22 carbon atoms in the molecule. Styrene or α-methylstyrene can also be contained in the polymer in secondary amounts, ie in amounts of less than 20% by weight.

Polymer P1 can therefore be modified with other hydrophobic vinyl compounds, such as very polar strong monomers 11 such as acrylamide, acrylonitrile, maleic anhydride, maleic acid, p-(2-hydroxyhexyl), etc. The content of styrene or allyl alcohol (fluorinflovir) is very limited. This polar monomer-containing polymer P
It should be less than 10% by weight or less than 531% by weight of 1. Particular preference is given to those polymers A which contain less than 0,R% by weight of these polar monomers.

The content of monomer H in the polymer P2 likewise depends on the degree of compatibility desired and is at least 30% by weight, generally at least 50% by weight, advantageously at least 70% by weight and in particularly advantageous embodiments >95x The amount is %. For many applications, it is highly advantageous to use a homopolymer of monomer H for the production of polymer 2.

As comonomers for constructing the electropolymer P2t-, in addition to the monomer of formula (1), the monomers listed for the active polymer P1 can be mentioned, but in this case, the use of extremely polar monomers is especially restricted. (generally polar monomers are limited to a content of <20% by weight, preferably <5% by coul).

Polymer P2t - mainly (>50% by weight) - but not up to 100% of the constituent monomers of formula H,
Vinyl esters, vinylamides, vinyl carbonates, vinylurethanes and vinylureas derived from the formula... and the corresponding propenyl compounds are mentioned.

Furthermore, the monomer of formula ■ is itaconic acid amine), +! and esters. However, preferred monomers are esters of acrylic acid and methacrylic acid and hyaluronan. Very generally, as already mentioned, esters are particularly preferred.

When nitrogen-containing basemers of the formula (1) are used, those having no IIIH group are advantageous. In particular, monomers of formula (2) include optionally substituted vinyl- or gropenyl esters of dichloroalkane carboxylic acids and cycloalkyl carbonates, cycloalkyl acrylates, Schifftetraalkyl methacrylates and cycloalkyl itaconates, optionally substituted vinyl esters-or hapropenyl esters of phenylalkyl carboxylic acids and phenylalkyl carbonates,
Phenylalkyl acrylate, 7-enylalkyl methacrylate and phenylalkyl itaconate. Mention may especially be made of cyclohexyl acrylate and cyclohexyl methacrylate. However, care should always be taken that the monomers of the formula H of the polymer P1 and the monomers of the formula . . . of the polymer P2 appear to be the same.

In other words, the repulsion of the subunits of the monomer constituent ■ and the spatial expansion (7 Onderwaalska) of the substandard of the monomer constituent ■ lead to the repulsion of the subunits of the monomer constituent ■ and its spatial expansion. It should always be proportional.

In other words, for example, poly pt-butylstyrene (k-merged P
1) has a significant sterically ordered aliphatic moiety (t-butyl group) next to the phenylene group.Thereby, the aliphatic and aromatic moieties of this monomer unit present The significant repulsion between poly pt-butylstyrene makes it an ideal blending component for polymer P2, with the only limitation being that polymer P2 also has significant b content in its monomer constituents. A large (best branched) aliphatic group -0HR,SR with repulsion, i.e. a large (best branched) aliphatic group next to the polar group

Therefore, poly pt-butylstyrene (polymer Pi) is unconditionally compatible with poly-393@5-17methylcyclohexyl acrylate, which has a high steric order (
Regarding the mixing range 1:99-99:IK). Complete compatibility was found over the entire temperature range used empirically in polymer mixtures PM (ie up to >250° C.).

Polymeric polymers PM according to the invention with unconditional compatibility
Examples include: Polymer P1 having units Polymer P2 During the description of the examples, six other examples are given in which poly-p is used as a model system.
Using -t-butylstyrene, the excellent compatibility of bo13-p-t-butylstyrene as polymer P1 with polymer P2 is demonstrated.

Unlike BoIJ-p-t-butylstyrene as polymer P1, Bo17-p-methylstyrene has a significant aliphatic moiety next to the phenylene group, i.e. the repulsion of the groups inside the polymer component is It is extremely small. Therefore, the range of change inside the summer coalescence P2 is also small. For this reason, poly-17+p-methylstyrene is completely incompatible with the poly-t-trimethylcyclohexyl acrylate. In contrast, complete compatibility was found using polycyclohexyl acrylate as polymer P2. (
(Both p-methylstyrene and polycyclohexyl acrylate have a quaternary atom in the alkyl group; they are geometrically comparable).

On the other hand, Bo')-p-tbutylstyrene(

There is only a markedly reduced compatibility tW. Although these polymers are still fully compatible at room temperature, separation occurs upon heating to about 80°C.

Examples of polymer mixtures according to the invention with unconditional compatibility are: Polymer P1 Polymer P2 with units In addition to this polymer mixture which is compatible in all temperature ranges and all mixing ratios: Also advantageous are polymer mixtures PM which are compatible and only soften within a limited temperature range (for example 100° C.).

The mixing ratio of general IC3 aggregate P1 to polymer P2 can be varied within a wide range. That is, the λ-combined polymer PM according to the present invention is generally composed of two polymers P10, R to 99.9% by weight, consisting of about 60% by weight of a polymer P1 of the formula (2) and B) the formula H. Polymer P299, R~0, consisting of at least about 30% by weight of R.

In particular, polymer P1 about 1 to 99 weight 7o and polymer P2 about 9
Preference is given to polymer mixtures consisting of 9 to 1 Nfk%. About 10-901% of polymer P1 and about 9% of polymer P2
Particular preference is given to such polymer mixtures consisting of 0 to 10 i% by weight. Finally, polymer mixtures consisting of about 20 to 80 weight % of polymer P1 and about 80 to 2 weight % of polymer P2 are very particularly preferred. The composition of the polymer mixture PM then depends on the respective technical requirements (see below).

Polymer P1 may also contain monomers of formula H or polymer P1 may also contain monomers of formula H.
Whether 2 can contain monomers of formula 1 also depends on the technical requirements of the application. In principle, it is reasonable that the content of the monomer of formula I in the polymer P1 is at least 303% higher than the content of the formula I in the polymer P2. Similarly, the content of monomers of formula H in polymer P2 is higher than the content of monomers of formula H in polymer P1 by at least 3ON%. The content of monomers of formula I in polymer P2 is <10% by weight, very particularly 0% by weight, and the content of monomers of formula I in polymer P1 is likewise <10% by weight, very particularly Particular preference is given to polymer mixtures which are in particular 0.01i%.

Generally, the content of the monomer of formula I in polymer P1 and the content of the polymer of formula I in polymer P2 are such that the remaining components in polymer P1 and the remaining components in polymer P2 It can be said that the amount may be particularly small if there is a sufficient chemical match.

The characterization of the polymeric polymer PM according to the invention as a compatible mixture is carried out according to generally accepted criteria (cf. Kirkoosmer, supra, Vol. 18, pp. 457-460).

The radical method is preferably used, but it is also possible to use the ionic method. The molecular itM of the polymers P1 used according to the invention is generally above 6000, preferably in the range from 5000 to 10.0000, particularly preferably in the range from 20000 to 5ooooo. (Measurement by light scattering). In any case, it is emphasized that the molecular weight does not seem to have a decisive influence on its suitability as a component in the compatible polymer mixture PM.

This also applies to homopolymers as copolymers of the Pl and P2 types. The tactility of the polymers is important to some extent for the compatibility of the polymers P1 and P2. In general, polymers P2 with a lower isotactic trier content (such as those obtained by radical polymerization) are better than polymers with a higher isotactic content (such as those produced by special ionic polymerization). is also particularly advantageous.

The homopolymer or copolymer P2 is generally produced by radical polymerization. (H, Rauch-Puntigam, Th.

, preferably in the range from 20,000 to 300,000. When selecting the monomer components used as comonomers in P2, care should be taken that the glass temperature T of the resulting polymer does not have a limiting effect on the industrial applicability of the overall PM system. .

In other words, in order to create a molded body from the polymer polymer PM, K

7. For this use it is advantageous for the polymer mixture PM to also have a glass temperature Tg>70° Cf. This limitation can be said to be advantageous for producing injection-molded, compression-molded or extruded articles from the polymer mixture PM. However, there are other fields of use, such as for paints, elastomers or reversible endothermic vitrification (polymer polymers with a busy cloud point when heated) and German Patent (DF)-A) No. 34 36 477.3. For use with k, preference is given to polymer mixtures PM such that the polymer component P2 has a glass temperature T <40° C. or preferably 20° C.

Creation of Mixtures PM Compatible mixtures PM can be produced by botanical methods. This mixture is, for example, the components P1 and P2' of the melt.
can be produced in extruders etc. by intensive mechanical mixing, or from common solvents, so-called
It can also be produced as a "solution cast polyblend".

(See Kirkoo Osmer 1 Encyclopedia Oschemical Technology' 3rd edition, Vol. 18, pp. 446-478, J. Riley, 1982). Polymer P1 is bath-dissolved into a mass polymer of other polymer P2, and then polymer P
It is also possible to produce K in the presence of 1. Conversely, it is of course also possible to produce blood complex P1 in the presence of polymer P2. Polymer mixtures PM can likewise be obtained from a common precipitant. There are no restrictions on mixed types. A very good overview of the preparation of compatible polymer mixtures can be found in the aforementioned book ``Bolymers Planes and Mixtures''.
M. T. Shaw, pp. 7-67.

As a rule, first a mixture of components P1 and P2 is prepared, preferably starting from a solid, e.g. -1 double chamber - carried out using a Pflugscharmiacher or the like. A slowly operating mixing device produces mechanical mixing without increasing the phase interface. (See Urmans Encyclopedia Der Technitzien Hiemi, 4th edition, Vol. 2, pp. 282-311, Verlag Hiemi). The thermoplastic preparation is then carried out in the melt using a heatable mixing device at a temperature suitable for this purpose, for example from 150 to about 300° C., in a kneader or, preferably, in an extruder.
For example, in a screw or multi-screw extruder or in an extruder optionally with driving screws and shear studs, such as a Pasco kneader (Bu8scO-Kneter).
) by mixing the mixture uniformly.

This method produces uniform granules (e.g. Hθ1 blood bachlag cubic, round particles').
It can be made by TW. At that time, the particle size of the granules is 2 to 5.
H range. Another common method for producing the polymeric compound PM is the mixing of a polymer dispersion containing the polymer component P1t and a polymer dispersion containing the polymer component P2. The dispersion mixture can be coagulated together, spray dried together or crushed together in an extruder.

Effect The compatible λ polymer mixture PM according to the invention has, in particular, the following advantages, which suggest a corresponding possibility of use in polymers, in which case P1 or P2 is, respectively, a polymer P1 or This represents the possibility of belonging to P2.

1. First, the polymer mixture is - a mixture consisting of another carbonyl group-containing polymer P1 and another polystyrene;
Unlike other products, it is a one-phase bath.

In other words, the polymer mixture PM according to the invention is glass-transparent in the pigmented state, unlike incompatible polymer mixtures (this mixture has no light scattering, i.e. usually has very low light scattering). 10%). However, according to the invention, mixtures that are compatible only at room temperature will separate when the temperature is increased.

2. The mixture of Pl and P2, like polystyrene itself, absorbs only a small amount of water.

3. The birefringence of polymer P1 is reduced by mixing with P2. Both of the abovementioned properties qualify the stone-type coalescent mixture PM according to the invention as a data storage material, especially for optically readable information carriers. [J.

In general, the refractive index of the polymer P1 can also be reduced by mixing it with P2. For example, Pl can be mixed with P2 to change its refractive index such that the refractive index of the polymeric polymer PM matches the refractive index of the deposited rubber phase. In this way a transparent impact-resistant plastic is obtained.

In particular, it consists of about 40 to 99% by weight, advantageously 70 to 95% by weight of the polymeric compound PM, and is chemically distinguishable from Pl and P2 by up to 60 to ix% by weight, advantageously from 60 to 5% by weight. It has also been found advantageous to use polymer compositions consisting of other polymers P3 which can
and is incompatible with the mixture PM.

In this case, the composition of the polymer mixture PM is generally selected such that the refractive index of the polymer P3 corresponds to the refractive index of the mixture PM;
Therefore, the following should be taken at general building room temperature: In general, polymers that are incompatible with PM have a total temperature of 20°C,
It is at least partially covalently bonded to at least one of the components of the polymer mixture PM, thus Pl or P2. Furthermore, polymer P6 may be crosslinked.

It is particularly advantageous if the polymer P3 is polybutadiene or polyisoprene.

PM4[]~99! Polymer compositions consisting of 1% to 30% by weight of P3 and P3 are distinguished by improved impact strength compared to pure PM, especially when P6 has T and 20°C.

In particular, a polymer composition consisting of % PM4Q-99]i and P660-11% by weight produces a simple high-impact mixture of polymer P2.

5. By cutting out Pl with P2, for example, optical gradient fibers with the following arrangement are obtained.
Entenfaser ) can be produced: Nucleus: P
1, Subject a: P2, Progress: Continuous Generally nD20P1>np20P2.

This cypress fiber can be used, for example, as a light conductor wire.

6. Objects made of Pl with a thin coating of P2, especially P2 with a (partially polymerized) UV absorber, are also available. This plant material is weather resistant in contrast to uncovered Pl. Due to the good compatibility, the waste can be remixed, so that there are no disadvantages other than the reuse of heterogeneous plastic waste. In general, objects made of Pl or polymeric material PM can be produced by injection, compression, extrusion,
Manufactured by roller or casting. Extraction of polymer P2 is generally carried out by coating or by coextrusion.

7. A plate made of Pl with a cover made of P2 is manufactured. A plate with this structure has an improved light transmission of up to 2% compared to an untreated plate made of Pl. In general, plated plates consisting of P2 have better scratch resistance and altered corrosion resistance. For example, it is used for glazing greenhouses.
Particular preference is given to multiphase web plates made from Pl or the polymeric polymer PM and having a coating consisting of P2.

It is also possible to apply the molded body consisting of CP1 to the polymer P2 or to a monomer/initiator mixture which preferably contains the monomer 1. In this case, a high polymerization rate of monomer (1) (particularly in the case of R3-H) can be combined with good polymer compatibility.

8. Mixture PMf consisting of Pl >90% by weight and P2 <10% by weight: process-technical advantages are obtained when used. In this case P2 plays the role of a processing aid. This is particularly advantageous for polymers P1 with R1-methyl.

9 From the polymer mixture PM according to the invention, a transparent material is modified in such a way that, by energy action on the surface, for example by suitable radiation, the polymer P1 with R1m0H3 is decomposed, but the polymer P2 with R3-hydrogen is not decomposed. A molded body can be obtained. (Mouldings, resists with surfaces with reduced reflection). Similarly, by using KR1-H or R3-OH3, molded bodies with reduced reflection can be produced.

In this case, the polymer 2 can be decomposed by the action of energy.

10. The polymeric polymers PM according to the invention, which have only limited compatibility, have been found to be particularly advantageous. L(:!ST
Compatible polymeric compounds which become light scattering when heated to a higher temperature are disclosed in West German Patent (DI-A) No. 34364.
Vitrification with temperature-controlled transparency for producing optically readable information according to No. 76.5 or with temperature-controlled transparency according to West German Patent (DB-A) No. 3436477.3 It can be advantageously used to produce a Verglasung system.

In general, there is a large difference in the refractive index between polymers P1 and P2 and hence strong light scattering in the case of separation and R
The wide possibility of varying the sizes of 1, R2, R3, R5, R6 and X makes the polymer mixture PM according to the invention particularly suitable for this range of use. (See example polypt-butylstyrene/polycyclohexyl acrylate).

Next, the present invention will be explained in detail with reference to Examples, but the present invention is not limited thereto. In this case, poly-p-t, butylstyrene (-R1-H and R2-t, butyl With polymer P1) a wide range of compatibility is offered, especially with polymer P2 containing the carbonyl groups of polymer P1.

On the other hand, in the example of 17-p-methylstyrene which represents a limit of the scope of the invention as a polymer P1 with R2-methyl (polystyrene: R3-hydrogen does not belong to the invention or also represents a limit of the invention). However, it is once again pointed out that the compatibility limit range (see 10 above) is also particularly advantageous from the point of view of the technology of use.
