Abstract

The invention relates to a solid stabilizer composition that comprises at least one onium perchlorate and one aminouracil, for use with preferably halogen-containing polymers.

Description

Solid stabilizer composition, its manufacture and use

The present invention relates to a solid stabilizer composition for halogen-containing polymers which contains at least one organic perchlorate and an aminouracil, their preparation and their use.

As is known, halogen-containing plastics tend to undergo undesirable decomposition and degradation reactions when subjected to thermal stress during processing or in long-term use. The degradation of halogenated polymers, especially PVC, produces hydrochloric acid, which is eliminated from the polymer strand, which results in a discolored, unsaturated plastic with coloring polyene sequences.

It is particularly problematic that halogen-containing polymers only have the theological framework necessary for processing at a relatively high processing temperature. At such temperatures, however, a noticeable decomposition of the polymer already begins in the case of unstabilized polymers, which leads both to the undesired color change described above and to a change in the material properties. In addition, the hydrochloric acid released from unstabilized, halogen-containing polymers at such a processing temperature can lead to noticeable corrosion of the processing plants. This process plays a role in particular when, during the processing of such halogenated polymers to give shaped articles, for example by extrusion, production is interrupted and the polymer mass remains in the extruder for a longer period of time. During this time, the above-mentioned decomposition reactions can occur, rendering the batch in the extruder unusable and possibly damaging the extruder.

Furthermore, polymers which are subject to such decomposition tend to form attachments to the processing plants which are difficult to remove. In order to solve the above-mentioned problems, halogen-containing polymers for processing are usually added as "stabilizers", which are intended to prevent the above-mentioned decomposition reactions as far as possible. Generally, such stabilizers are solids which the polymer to be processed before it Processing can be added.

Suitable stabilizers are, for example, perchlorates, the perchlorates according to the prior art generally being used as inorganic perchlorates, for example as sodium perchlorate. However, the problem with these connections is that they do not always meet the requirements placed on them. Liquid perchlorates, for example, have the disadvantage that special requirements are placed on the metering, in particular that the metering units have to be specially matched to the liquids. In addition, liquid components in solid stabilizer compositions lead to an increased tendency to stick.

The unpublished German patent application with the file number 101 18 179.5 relates to stabilizer compositions which contain organic perchlorates.

The object of the present invention was therefore to provide a solid stabilizer composition which can be used in the production of halogen-containing polymers and which leads to an excellent initial color and excellent color retention. The invention was also based on the object of providing a solid stabilizer composition which shows an improvement in the initial color and the color retention when processing halogen-containing polymers in comparison with stabilizers known from the prior art.

It has now been found that solid stabilizer compositions which contain at least one organic onium perchlorate and an aminouracil achieve the above-mentioned objects.

A first object of the present invention is therefore a solid stabilizer composition comprising an organic onium salt of perchloric acid or a mixture of two or more organic onium salts of perchloric acid and 0.01 to 80% by weight of an aminouracil compound of the general formula I

R ³

wherein the radicals R ¹ and R ³ each independently represent hydrogen or a linear or branched, saturated or unsaturated, substituted or unsubstituted alkyl radical having 1 to 22 carbon atoms or a saturated or unsaturated, substituted or unsubstituted cycloalkyl radical having 6 to 18 carbon atoms or a substituted or unsubstituted aromatic hydrocarbon radical with 6 to 44 C atoms and the radical R ² for hydrogen, an optionally substituted linear or branched, saturated or unsaturated aliphatic hydrocarbon radical with 1 to 44 C atoms, an optionally substituted saturated or unsaturated cycloaliphatic hydrocarbon radical having 6 to 44 carbon atoms or an optionally substituted aromatic hydrocarbon radical having 6 to 44 carbon atoms, or a mixture of two or more thereof.

In the context of the present invention, a “stabilizer composition” is understood to mean a composition which can be used to stabilize halogen-containing polymers. To achieve this stabilization effect, a stabilizer composition according to the invention is generally mixed with a halogen-containing polymer provided for stabilization and then processed. However, it is also possible to add a stabilizer composition according to the invention to the halogen-containing polymer to be stabilized during processing.

In the context of the present text, an "onium salt" is a compound which is an ammonium, sulfonium or phosphonium salt. With an "onium salt" according to The present invention is an organic onium salt. This means that the ammonium, sulfonium or phosphonium group of the onium salt carries at least one organic radical. An onium salt according to the present invention can, depending on the type of onium group, carry 1, 2, 3 or 4 organic radicals. The organic radicals can be connected to the onium radical, for example via a CX linkage, where X stands for S, N or P. However, it is also possible for the organic radicals to be connected to the onium radical via a further hetero atom, for example an O atom.

An onium perchlorate which can be used in the context of the present invention has at least one positively charged N, P or S atom or two or more such positively charged N, P or S atoms or mixtures of two or more of the positively charged atom types mentioned on.

In the context of the present invention, compounds are used as onium perchlorates which carry at least one organic radical on the N, S or P atom and at most the maximum possible number of organic radicals. If an onium perchlorate which can be used according to the invention carries fewer organic residues than are necessary for the formation of a positively charged onium ion, the positive charge is generated in a conventional manner known to the person skilled in the art by protonation using a suitable acid, so that the corresponding onium perchlorate in this case in addition to an organic residue carries at least one proton.

It is therefore possible according to the invention to use compounds as onium perchlorates which have a positive charge due to protonation reactions. However, it is also possible in the context of the stabilizer combinations according to the invention to use onium perchlorates which have a positive charge as a result of a peralkylation reaction. Examples of such compounds are tetraalkylammonium, trialkylsulfonium or tetraalkylphosphonium perchlorates. However, it is also provided in the context of the present invention that a peralkylated onium perchlorate which can be used according to the invention has an aryl, alkaryl, cycloalkyl, alkenyl, alkynyl or cycloalkenyl radical. It is also possible and provided according to the invention that an onium salt which can be used in the context of a stabilizer composition according to the invention has two or optionally more different types of substituents, for example an alkyl and a cycloalkyl radical or an alkyl and an aryl radical.

It is also possible and provided in the context of the present invention that an onium salt which can be used in the context of a stabilizer composition according to the invention has substituents which in turn are substituted by one or more functional groups. "Functional groups" are groups which improve the effects of the stabilizer composition or at least not or only insignificantly worsen them. Corresponding functional groups can be, for example, NH groups, NH ₂ groups, OH groups, SH groups, ester groups, ether groups, thioether groups, isocyanurate groups or keto groups or mixtures of two or more thereof.

In principle, all compounds which lead to a phosphonium perchlorate by appropriate reaction of suitable reactants can be used as phosphonium perchlorates in the context of the present invention. Phosphonium perchlorates which can be used according to the invention can be obtained, for example, by appropriate reaction of tetraalkyl, tetracycloalkyl or tetraaryl phosphorus halides. Suitable phosphonium perchlorates are therefore derived, for example, from tetraalkylphosphorus salts such as tetra-n-ethylphosphonium bromide, tetra-n-propylphosphonium bromide, tetra-n-butylphosphonium bromide, tetra-n-isobutylphosphonium bromide, tetra-n-pentomyl, tetra-n-pentomyl - Phonium bromide and the like tetraalkyl phosphorus salts. Furthermore, phosphonium perchlorates which are derived, for example, from tetracycloalkyl phosphorus salts or tetraaryl phosphorus salts are suitable in principle for use in the stabilizer compositions according to the invention. Suitable phosphonium perchlorates are therefore based, for example, on tetracycloalkyl or tetraaryl phosphorus salts such as tetracyclohexylphosphonium bromide or tetraphenylphosphonium bromide and the like tetracycloalkyl or tetraaryl phosphorus salts. The abovementioned compounds can be unsubstituted in the context of the present invention, but they can also have one or more of the abovementioned substituents, provided that these substituents are used in the context of the stabilizer additions. composition have no adverse effects and do not adversely affect the intended use of the stabilizer composition.

Organic phosphonium perchlorates which carry different types of organic substituents on a phosphorus atom, which can optionally be substituted differently, can also be used in the context of the present invention.

In a preferred embodiment of the present invention, tetra-n-butylphosphonium perchlorate or triphenylbenzylphosphonium perchlorate are used as phosphonium perchlorates.

In principle, all compounds which lead to a sulfonium perchlorate by appropriate reaction of suitable reactants can be used as sulfonium perchlorates in the context of the present invention. Sulfonium perchlorates which can be used according to the invention can be obtained, for example, by appropriate reaction of sulfides such as alkyl monosulfides, alkyl disulfides, dialkyl sulfides or poly (alkyl sulfides). Suitable sulfonium perchlorates are therefore derived, for example, from dialkyl sulfides such as ethylbenzyl sulfide, allylbenzyl sulfide or alkyl disulfides such as hexane disulfide, heptane disulfide, octane disulfide and the like alkyl disulfides. Furthermore, sulfonium perchlorates which are derived, for example, from tricycloalkylsulfonium salts or triarylsulfonium salts are suitable in principle for use in the stabilizer compositions according to the invention. Suitable sulfonium perchlorates are therefore based, for example, on tricycloalkyl or triarylsulfonium salts such as tricyclohexylsulfonium bromide or triphenylsulfonium bromide and the like tricycloalkyl or triarylsulfonium salts. Trialkyl, triaryl or tricycloalkylsulfoxonium salts such as trimethylsulfoxonium perchlorate are also suitable. The abovementioned compounds can be unsubstituted in the context of the present invention, but they can also have one or more of the abovementioned substituents, provided that these substituents have no adverse effects in the context of the stabilizer composition and do not adversely affect the intended use of the stabilizer composition. Organic sulfonium perchlorates which have different types of organic substituents on a sulfur atom and which may be substituted differently can also be used in the context of the present invention.

In a preferred embodiment of the present invention, trimethylsulfoxonium perchlorate is used as the sulfonium perchlorate.

In a further embodiment of the present invention, the perchlorates of heterocyclic compounds are used as ammonium perchlorates, which have a cyclic ring system having amino groups.

For example, the perchlorates of heterocyclic amino alcohols are used which have at least 2, preferably at least 3 amino groups in the ring. The trimerization products of isocyanates are particularly suitable as the central ring component of the ammonium perchlorates which can be used according to the invention.

For example, hydroxyl-containing isocyanurates of the general formula II are suitable CHYOH

wherein the groups Y and the indices m are each the same or different and m is an integer from 0 to 20 and Y is a hydrogen atom or a linear or branched, saturated or unsaturated alkyl group having 1 to about 10 carbon atoms. The use of tris (hydroxymethyl) isocyanurate (THEIC) as a constituent of the stabilizer compositions according to the invention is particularly preferred in the context of the present invention.

Also suitable as ammonium perchlorates are, for example, compounds in which the amino group is bound to a substituted aromatic or heteroaromatic system, for example aminobenzoic acid, aminosalicylic acid or aminopyridinecarboxylic acid and their suitable derivatives.

In the context of the present invention, a stabilizer composition according to the invention can contain, for example, only one of the above-mentioned onium perchlorates. In the context of the present invention, it is also possible and also provided that a stabilizer composition according to the invention is a mixture of two or more of the above contains called onium perchlorates. It can be a mixture of two or more different types of onium perchlorates, ie for example a mixture of ammonium perchlorates and sulfonium perchlorates or ammonium perchlorates and phosphonium perchlorates or sulfonium perchlorates and phosphonium perchlorates or ammonium perchlorates and sulfonium perchlorates and phosphonium perchlorates. It is also possible within the scope of the invention that a stabilizer composition according to the invention contains a mixture of two or more onium perchlorates of one type, ie a mixture of two or more ammonium perchlorates and a mixture of two or more sulfonium perchlorates and a mixture of two or more phosphonium perchlorates ,

If a stabilizer composition according to the invention contains a mixture of two or more onium perchlorates, these two or more onium perchlorates can in principle be present in any ratio in the stabilizer composition according to the invention.

Within the scope of the present invention, a stabilizer composition according to the invention contains, based on the total composition, from 0.01 to about 30% by weight, for example from about 0.1 to about 20% by weight, of an organic onium salt of a perchlorate or a mixture of two or more organic onium salts of perchlorates.

In the context of the present invention, a stabilizer composition according to the invention preferably contains an ammonium or a sulfonium perchlorate or a mixture of two or more thereof, in particular an ammonium perchlorate, for example an ammonium perchlorate of an amino alcohol with 2 or 3 OH groups, as organic onium perchlorate.

Since many of the onium perchlorates which can be used in the context of the present process and in a stabilizer composition according to the invention are not commercially available and therefore have to be prepared by the user himself, the process is suitable for To integrate production of the onium perchlorates into the process according to the invention for producing the stabilizer composition according to the invention. Different procedures can be selected for this, of which a selection is described below as an example.

For example, it is basically possible, first of all, to produce an onium perchlorate from an organic compound capable of forming an onium salt or a salt of such a compound by reaction with perchloric acid or a suitable inorganic salt of perchloric acid. The reaction is preferably carried out in aqueous solution, the perchloric acid or the corresponding suitable salt of perchloric acid usually being added dropwise as an aqueous solution with a concentration of about 50 to about 70% by weight. If it is insoluble in water, the onium perchlorate formed can be separated off as a precipitate using customary separation methods, for example filtration or centrifugation.

If the organic compound used to form an onium salt forms a water-insoluble organic perchlorate, either perchloric acid or, as an inorganic salt of perchloric acid, an alkali perchlorate, for example sodium perchlorate or potassium perchlorate, is reacted with an onium chloride in aqueous solution. This creates a water-insoluble organic onium perchlorate and a water-soluble alkali chloride. The water-insoluble organic onium perchlorate can be separated off in the usual way. If necessary, water can also be removed from the organic onium perchlorate in an intermediate step.

If the organic compound used to form an onium salt forms a water-soluble organic perchlorate, a compound which forms a water-insoluble chloride is used as the inorganic salt of perchloric acid. The water-insoluble chloride can be separated off in the usual way. The soluble onium perchlorate can then be freed of water in the usual way.

A water-soluble organic onium chloride and, for example, silver perchlorate as an inorganic salt of perchloric acid can also be used as the organic compound capable of forming an onium salt. If the water-soluble organic onium chloride If silver perchlorate is added in aqueous solution, an insoluble silver chloride forms a precipitate and an aqueous solution of an organic onium perchlorate is formed. The precipitate is then filtered off and the organic onium perchlorate in aqueous solution is isolated by customary separation methods, for example by distilling off the water.

However, the production of an onium perchlorate and a stabilizer composition according to the invention is not only possible from an aqueous solution. It is also possible to produce an appropriate onium perchlorate from organic solution.

For this purpose, an aqueous solution of an organic compound capable of forming an onium salt or a salt of such a compound is mixed with aqueous perchloric acid or an aqueous solution of an inorganic salt of perchloric acid. An organic onium perchlorate is formed, which remains in the organic solution. It is possible to work both in organic solvents that are not miscible with water and in organic solvents that are miscible with water. The water and optionally the organic solvent are then removed from the mixture.

A stabilizer composition according to the invention also contains 0.01 to 80% by weight of an aminouracil compound of the general formula I.

1) 16.67 g of a 60% perchloric acid were added dropwise to a solution of 19.13 g of triisopropanolamine in 100 ml of water. The contained solution of triisopropanolammonium perchlorate in water was evaporated to dryness in a rotary evaporator. 29.1 g of triisopropanolammonium perchlorate (perchlorate content: 34%) were isolated.

2) In an alternative production of triisopropanolammonium perchlorate, 38.26 g of triisopropanolamine were melted and 33.3 g of a 60% strength aqueous perchloric acid were added at 85.degree. The water-containing reaction melt obtained was then freed from the water in vacuo. The melt obtained from After cooling, triisopropanolammonium perchlorate gave 58.0 g of crystalline triisopropanolammonium perchlorate (perchlorate content: 34%).

3) 16.7 g of an aqueous, 60% pure perchloric acid were added dropwise to a solution of 14.9 g of triethanolamine in 100 ml of water with stirring. The resulting solution of triethanolammonium perchlorate was freed of water in a rotary evaporator. 24.8 g of triethanolammonium perchlorate were obtained as a solid (perchlorate content: 40%).

4) Because of the comparatively low softening point of the products from Example 1 or Example 2, the product from Example 2 was melted in a ratio of 4:75 with zeolite and cooled with stirring. A free-flowing powder was obtained.
