where the substituents may have the following meanings:

R ^{10 is} hydrogen or a C 1 -C ₄ -alkyl group,

R ^{11 is} hydrogen, a C 1 -C ₈ -alkyl group or an aryl group, in particular phenyl,

R ¹² is hydrogen, a Ci-Cio-alkyl, a _C6-Ci2 aryl group, or -OR ¹³

R ¹³ is a Ci-C ₈ -alkyl or C ₆ -C ₂ aryl group which may be substituted by O- or N-containing groups,

X is a chemical bond, a CrClio-alkylene or

or

O

- c - Y

Y OZ or NH-Z and Z is a Ci-Cio-alkylene or C ₆ -C ₂ arylene group.

The graft monomers described in EP-A 208 187 are also suitable for introducing reactive groups on the surface.

Further examples which may be mentioned are acrylamide, methacrylamide and substituted esters of acrylic acid or methacrylic acid, such as (Nt-butylamino) -ethyl methacrylate, (N, N-dimethylamino) ethyl acrylate, (N, N-dimethylamino) -methyl acrylate and (N, N-diethylamino) ethyl acrylate called.

Furthermore, the particles of the rubber phase can also be crosslinked. Examples of monomers acting as crosslinking agents are buta-1,3-diene, divinylbenzene, diallyl phthalate and dihydrodicyclopentadienyl acrylate and also the compounds described in EP-A 50 265.

Furthermore, so-called graftlinking monomers can also be used, i. H. Monomers having two or more polymerizable double bonds, which react at different rates in the polymerization. Preferably, those compounds are used in which at least one reactive group polymerizes at about the same rate as the other monomers, while the other reactive group (or reactive groups) z. B. polymerized much slower (polymerize). The different polymerization rates bring a certain proportion of unsaturated double bonds in the rubber with it. If a further phase is subsequently grafted onto such a rubber, the double bonds present in the rubber react at least partially with the graft monomers to form chemical bonds, ie. H. the grafted phase is at least partially linked via chemical bonds to the graft base.

Examples of such graft-crosslinking monomers are allyl-containing monomers, in particular allyl esters of ethylenically unsaturated carboxylic acids such as allyl acrylate, allyl methacrylate, diallyl maleate, diallyl fumarate, diallyl itaconate or the corresponding monoallyl compounds of these dicarboxylic acids. In addition, there are a variety of other suitable graft-linking monomers; for closer individual rides, reference is made to US Pat. No. 4,148,846, for example.

In general, the proportion of these crosslinking monomers in the impact-modifying polymer is up to 5% by weight, preferably not more than 3% by weight, based on the impact-modifying polymer. In the following, some preferred emulsion polymers are listed. First, graft polymers having a core and at least one outer shell, which have the following structure:

Instead of graft polymers with a multi-shell structure can also homogeneous, d. H. single-shell elastomers of buta-1, 3-diene, isoprene and n-butyl acrylate or copolymers thereof are used. These products can also be prepared by concomitant use of crosslinking monomers or monomers having reactive groups.

Examples of preferred emulsion polymers are n-butyl acrylate / (meth) acrylic acid copolymers, n-butyl acrylate / glycidyl acrylate or n-butyl acrylate / glycidyl methacrylate copolymers, graft polymers having an inner core of n-butyl acrylate or butadiene-based and an outer shell of the above mentioned copolymers and copolymers of ethylene with comonomers which provide reactive groups.

The elastomers described can also be prepared by other conventional methods, for. B. by suspension polymerization. Silicone rubbers, as described in DE-A 37 25 576, EP-A 235 690, DE-A 38 00 603 and EP-A 319 290, are likewise preferred.

Of course, it is also possible to use mixtures of the rubber types listed above.

In addition, fillers and additives can also be used in the polymer formation. Suitable additives are known in the art. Examples of this are described in Hans Zweifel, Plastics Additives Handbook, 5th edition 2001, Carl Hanser Verlag. Suitable fillers are known to the person skilled in the art. Examples are in Katz, Harry S .; Milewski, John V. [Ed.], Handbook of Fillers for Plastics, 1987, Kluwer Academic Publishers Group.

In the context of the present invention, the term "polyolefin" encompasses all polymers which are built up from olefins without further functionality, such as low or high density polyethylene, polypropylene, linear polybutene-1 or polyisobutylene or polybutadiene and also copolymers of monoolefins or diolefins. Preferred polyolefins are the homopolymers and copolymers of ethylene and the homopolymers and copolymers of propylene.

Ethylene polymers:

Suitable polyethylene (PE) homopolymers are, for example:

-PE-LD (LD - low density), obtainable for example by the high pressure process (ICI) at 1000 to 3000 bar and 150 to 300 ⁰ C with oxygen or peroxides as catalysts in autoclaves or tubular reactors. Highly branched with branches of different lengths, crystallinity 40 to 50%, density 0.915 to 0.935 g / cm ³ , average molecular weight to 600 000 g / mol.

-PE-LLD (LLD = linear low density), obtainable with metal complex catalysts in the low-pressure process from the gas phase, from a solution (eg gasoline) in a suspension or with a modified high pressure process, weakly branched with unbranched side chains, molecular weights higher than PE-LD.

-PE-HD (HD = high density), available in the medium pressure (Phillips) and low pressure (Ziegler) processes. After Phillips at 30 to 40 bar, 85 to 180 ⁰ C, chromium oxide as a catalyst, molecular weights about 50 000 g / mol. After Ziegler at 1 to 50 bar, 20 to 150 ⁰ C, titanium halides, titanium esters or aluminum alkyls as catalysts, molecular weight about 200 000 bis 400 000 g / mol. Procedure in suspension, solution, gas phase or mass, very weakly branched, crystallinity 60 to 80%, density 0.942 to 0.965 g / cm ³ .

Particularly suitable is polyethylene, which is produced in a gas-phase fluidized-bed process using (normally supported) catalysts, for example Lupo len ^® (Basell).

Particularly preferred is polyethylene produced using metallocene catalysts. Such polyethylene eg ^® as Luflexen (Basell) are commercially available.

Suitable ethylene copolymers all commercially available ethylene copolymers are suitable, for example, Luflexen ^® grades (Basell), Nordel ^® and Engage ^® (Dow, DuPont). Suitable comonomers are, for example, α-olefins having from 3 to 10 carbon atoms, in particular propylene, but-1-ene, hex-1-ene and oct-1-ene, and also alkyl acrylates and methacrylates having from 1 to 20 carbon atoms. Atoms in the alkyl radical, in particular butyl acrylate. Other suitable comonomers are dienes such as butadiene, isoprene and octadiene. Other suitable comonomers are cycloolefins, such as cyclopentene, norbornene and dicyclopentadiene.

The ethylene copolymers are usually random copolymers or block or impact copolymers. Suitable block or impact copolymers of ethylene and comonomers are, for example, polymers in which in the first stage

Homopolymer of the comonomer or a random copolymer of the comonomer, for example, with up to 15 wt .-% ethylene produces and then in the second stage

Comonomer-ethylene copolymer with ethylene contents of 15 to 80 wt .-% hinzupolymeri- Siert. In general, so much of the comonomer-ethylene copolymer is polymerized that the copolymer produced in the second stage in the final product is from 3 to 60

% By weight.

The polymerization for the preparation of the ethylene-comonomer copolymers can be carried out by means of a Ziegler-Natta catalyst system. However, it is also possible to use catalyst systems based on metallocene compounds or on the basis of polymerization-active metal complexes. Propylene polymers:

The term polypropylene is to be understood as meaning both homo- and copolymers of propylene. Copolymers of propylene contain subordinate amounts of monomers copolymerizable with propylene, for example O ₂ -Cs-Al k-1-enes such as ethylene, but-1-ene, pent-1-ene or hex-1-ene. Two or more different comonomers can also be used.

Suitable polypropylenes are i.a. Homopolymers of propylene or copolymers of propylene with up to 50 wt .-% of copolymerized other alk-1-enes having up to 8 carbon atoms. The copolymers of propylene are random copolymers or block or impact copolymers. If the copolymers d of propylene are of random structure, they generally contain up to 15% by weight, preferably up to 6% by weight, of other alk-1-enes having up to 8 carbon atoms, in particular ethylene, butylene. 1-ene or a mixture of ethylene and but-1-ene.

Suitable block or impact copolymers of propylene are, for example, polymers in which, in the first stage, a propylene homopolymer or a random copolymer of propylene with up to 15% by weight, preferably up to 6% by weight, of other alk-1 ene with up to 8 carbon atoms and then in the second stage, a propylene-ethylene copolymer having ethylene contents of 15 to 80 wt .-%, wherein the propylene-ethylene copolymer additionally further C ₄ -C ₈ -Alk- I -ene may contain, polymerized. In general, so much of the propylene-ethylene copolymer is polymerized that the copolymer produced in the second stage in the final product has a content of 3 to 60 wt .-%.

The polymerization for the production of polypropylene can be carried out by means of a Ziegler-Natta catalyst system. Particular preference is given to using those catalyst systems which, in addition to a titanium-containing solid component a), also have co-catalysts in the form of organic aluminum compounds b) and electron donor compounds c).

However, it is also possible to use catalyst systems based on metallocene compounds or on the basis of polymerization-active metal complexes.

The preparation of the polypropylenes is usually carried out by polymerization in at least one, often also in two or more successive reaction zones (reactor cascade), in the gas phase, in a suspension or in a liquid phase (Bulk phase). It is possible to use the customary reactors used for the polymerization of O ₂ -Cs-AIk-1-enes. Suitable reactors include continuously operated stirred tanks, loop reactors, powder bed reactors or fluidized bed reactors.

The polymerization for the preparation of the polypropylene used is carried out under conventional reaction conditions at temperatures of 40 to 120 ⁰ C, in particular from 50 to 100 ⁰ C and pressures of 10 to 100 bar, in particular from 20 to 50 bar.

Furthermore, the composition of the invention may contain other additives and additives. Suitable additives of group t) are the customary additives, such as. For example, pigments, dyes, nucleating agents, fillers or reinforcing agents, anti-fogging agents, biocides and antistatic agents into consideration.

Suitable pigments are inorganic pigments, for example titanium dioxide in its three modifications rutile, anatase or brookite, ultramarine blue, iron oxides, bismuth vanadates or carbon black and the class of organic pigments, for example compounds from the class of phthalocyanines, perylenes, azo compounds, isoindolines, quinophthalones, diketopyrolopyrols, Quinacridone, dioxazine, indanthrone.

Dyes are to be understood as meaning all colorants which dissolve completely in the plastic used or are present in a molecularly disperse distribution and can thus be used for the highly transparent, non-scattering coloring of polymers. E- benfalls as dyes organic compounds are to be regarded, which have a fluorescence in the visible part of the electromagnetic spectrum as fluorescent dyes.

Suitable nucleating agents include, for example, inorganic substances, for example talc, metal oxides such as titanium dioxide or magnesium oxide, phosphates, carbonates or sulfates of, preferably, alkaline earth metals; organic compounds such as mono- or polycarboxylic acids and their salts such. For example, 4-tert-butylbenzoic acid, adipic acid, diphenylacetic acid, sodium succinate or sodium benzoate; polymeric compounds, such as ionic copolymers ("ionomers"). Suitable fillers or reinforcing agents include, for example, calcium carbonate, silicates, talc, mica, kaolin, mica, barium sulfate, metal oxides and hydroxides, carbon black, graphite, wood flour and flours or fibers of other natural products, synthetic fibers. As examples of fibrous or powdery fillers are also carbon or glass fibers in the form of glass fabrics, glass mats or glass silk rovings, chopped glass, glass beads and wollstonite into consideration. The incorporation of glass fibers can take place both in the form of short glass fibers and in the form of continuous fibers (rovings).

Suitable antistatic agents are, for example, amine derivatives such as N, N-bis (hydroxyalkyl) alkylamines or -alkyleneamines, polyethylene glycol esters and ethers, ethoxylated carboxylic esters and amides and glycerol mono- and distearates, and mixtures thereof.

The incorporation of the additives and optional further components into the polymer is carried out by known methods, such as dry mixing in the form of a powder or wet mixing in the form of solutions, dispersions or suspensions, for example in an inert solvent, water or oil. The additives according to the invention and optional further additives can be incorporated, for example, before or after molding or else by applying the dissolved or dispersed additive or additive mixture to the polymer material, with or without subsequent evaporation of the solvent or of the suspension / dispersing agent. They may be added directly to the processing equipment (for example, extruders, internal mixers, etc.), for example as a dry mix or powder, as a solution, dispersion, suspension or melt, or as a masterbatch (e.g., dispersions in Luwax or other waxes).

The incorporation can be carried out in any heatable container equipped with a stirrer, for example in a closed apparatus, such as a kneader, mixer or stirred vessel. The incorporation is preferably carried out in an extruder or in a kneader. It does not matter if processing takes place in an inert atmosphere or in the presence of oxygen.

The addition of the additive or additive mixture to the polymer can be carried out in all conventional mixing machines wherein the polymer is melted and mixed with the additives. Suitable machines are known to the person skilled in the art. They are predominantly mixers, kneaders and extruders.

The process is preferably carried out in an extruder by introducing the additive during processing. Particularly preferred processing machines are single-screw extruders, co-rotating and counter-rotating twin-screw extruders, planetary gear extruders, ring extruders or co-kneaders. It is also possible to use processing machines that are equipped with at least one gas removal chamber to which vacuum can be applied.

Suitable extruders and kneaders are described, for example, in the Handbook of Plastic Extrusion, Volume 1 Fundamentals, Editors F. Hensen, W. Knappe, H. Potente, 1989, pages 3-7, ISBN: 3-446-14339-4 (Volume 2 Extrusion Plants 1986, ISBN 3-446-14329-7).

For example, the screw length is 1-60 screw diameter, preferably 35-48 screw diameter. The speed of rotation of the screw is preferably 10-600 revolutions per minute (rpm), more preferably 25-300 rpm. The maximum throughput depends on the screw diameter, the rotational speed and the driving force. The method of the present invention may also be practiced at a level below the maximum throughput by varying the mentioned parameters or using weighing devices that deliver the dosage amounts.

The incorporation may take place before or during a molding operation or by applying the dissolved or dispersed compound to the polymer with or without subsequent evaporation of the solvent. In the case of elastomers, these can also be stabilized as latexes. A further possibility for incorporating the additives according to the invention into polymers is to add them before, during or directly after the polymerization of the corresponding monomers or before crosslinking.

The composition of the present invention as described herein can be used in the manufacture of molds, rotational molded articles, injection molded articles, blow molded articles, films, tapes, monofilaments, fibers, nonwovens, profiles, adhesives or putties, surface coatings, and the like.

Possible applications include, for example, thermoplastic olefins, polypropylene molded articles, polyethylene film, agricultural mulch film polyethylene, molded articles

Alkyd refining enamels, electrocoating compositions, polycarbonate coatings, glydicylmethacrylate-based powder topcoats, preformed films for lamination to plastic substrates.

Also of particular interest is the use of the present composition for coatings, for example as paints. The invention therefore also relates to those compositions in which the polymer is a film-forming binder for coatings.

The binder may, in principle, be any binder customary in the industry, for example that described in Ullmann's Encyclopedia of Industrial Chemistry, 5th Edition, Vol. A18, pages 368 to 426, VCH, Weinheim 1991. In general, it is a film-forming binder based on a thermoplastic or thermosetting resin, predominantly on a thermosetting resin.
