Abstract

Description

Antistatic polymer composition, their preparation and

use

The present invention relates to an antistatic polymer composition, its preparation and its use.

As is known, halogen-containing plastics tend to undergo undesired decomposition and degradation reactions during thermal stress during processing or in long-term use. In the degradation of halogenated polymers, especially in PVC, hydrochloric acid is formed, which is eliminated from the polymer strand, resulting in a discolored, unsaturated plastic with coloring Polyensequenzen. A particular problematic aspect is that halogen-containing polymers only have the theological conditions required for processing at a relatively high processing temperature. At such temperatures, however, a noticeable decomposition of the polymer already occurs in the case of unstabilized polymers, which leads to both 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 significant corrosion of the processing equipment. This process plays a role in particular when production interruptions occur during the processing of such halogenated polymers into shaped articles, for example by extrusion, and the polymer composition lingers in the extruder for a relatively long period of time. During this time, the above-mentioned decomposition reactions may occur, making the batch in the extruder unusable, and possibly damaging the extruder. Furthermore, polymers that undergo such decomposition tend to form cling to the processing equipment that is difficult to remove.

To solve the problems mentioned, halogen-containing polymers for processing are usually added as so-called stabilizers compounds which should as far as possible prevent the abovementioned decomposition reactions. As a rule, such stabilizers are solids which are added to the polymer to be processed before it is processed.

Another problem in the production and use of moldings of halogen-containing polymers is that the moldings may have electrostatically unfavorable properties. To counteract these unfavorable properties, antistatics are therefore often added to the polymers. With the help of such antistatic agents, the tendency of polymers to load under mechanical stress, in particular friction, counteracted, or the rapid flow of the charge is ensured.

As antistatic agents, polymers are therefore frequently added with carbon blacks, PEG esters, glycerol mono- or distearates or, for example, also inorganic perchlorate compounds. While the former compounds often lacked in their antistatic effect, the perchlorates were usually intended for use in polymer compositions which serve to stabilize plastics.

For a variety of applications, however, there are unfavorable combinations of stabilization and antistatic behavior. It is an object of the present invention to provide a polymer composition which leads to an improvement in the discharge behavior. A further object of the present invention is to provide a polymer composition which has a suitable discharge behavior of the polymeric end product and which has little or no turbidity in the case of transparent end products, for example of hard or soft PVC. A further object of the invention was to provide a polymer composition which, on the one hand, gives the end product a good discharge characteristic and, moreover, has better heat stability.

It has now been found that polymer compositions containing at least one mixture of an organic ammonium perchlorate and an aminoalkanol solve the abovementioned objects.

A first subject of the invention is therefore a polymer composition comprising the following components: a) at least one halogen-containing polymer, b) at least one organic ammonium salt of a perchlorate or a mixture of two or more organic ammonium salts of perchlorates and c) at least one aminoalcohol with 2 to 12 C atoms in the alcohol radical, wherein the melting point of the amino alcohol 80 ⁰ C or less.

For the purposes of the present invention, a "polymer composition" is understood as meaning a composition which contains at least one stabilizer composition which is suitable for stabilizing halogen-containing polymers and moreover positively influences the discharge behavior of these halogen-containing polymers. In order to achieve this stabilizing and discharging effect, a corresponding stabilizer composition is generally mixed with a halogen-containing polymer intended for stabilization and then processed to give a polymer composition. However, it is also possible to add a stabilizer composition to the halogen-containing polymer to be stabilized during processing. In either case, the improved discharge characteristic from the addition occurs, it continues to act in the processed polymer.

The term "liquid" in the context of the present invention, the physical state of a stabilizer composition of the invention at least over a temperature range of about 45 to 100 ⁰ C, preferably over a temperature range of about 30 to about 12O ⁰ C, more preferably over a temperature range of about 15 to about 15O ⁰ C or more preferably over a temperature range of about 0 to about 200 ⁰ C understood.

An "ammonium salt" according to the present invention is an organic ammonium salt. This means that the ammonium group of the onium salt carries at least one organic radical. An ammonium salt according to the present invention may, depending on the nature of the ammonium group, carry 1, 2, 3 or 4 organic radicals.

An ammonium perchlorate which can be used in the context of the present invention has at least one positively charged N atom or two or more such positively charged N atoms.

In the context of the present invention, the ammonium perchlorates used are compounds which have at least one organic radical on the N atom and

- A - at most bear the maximum possible number of organic radicals. If an ammonium perchlorate which can be used according to the invention carries fewer organic radicals than necessary for the formation of a positively charged ammonium ion, the positive charge is generated in a conventional manner known to those skilled in the art by protonation by means of a suitable acid, such that the corresponding ammonium perchlorate is present in this case organic residue still carries at least one proton.

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

It is likewise possible and provided in the context of the present invention that an ammonium salt which can be used in the context of a polymer composition according to the invention has substituents which in turn are substituted by one or more functional groups. As "functional groups" are meant groups which improve the properties of the polymer composition in terms of antistatic behavior and stabilization against heat during processing or in long-term use, or at least not or worsen only insignificantly. 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.

As ammonium perchlorates, it is possible in principle to use all compounds which lead to an ammonium perchlorate by appropriate reaction of suitable reactants. In this case, ammonium perchlorates which can be used according to the invention can be obtained, for example, by appropriate reaction of amines or amides, such as alkylmonoamines, alkylenediamines, alkylpolyamines, secondary or tertiary amines or dialkylamines. Suitable ammonium perchlorates are therefore derived, for example, from primary mono- or polyamino compounds having from 2 to about 40, for example from 6 to about 20, carbon atoms. For example, these are ethylamine, n-propylamine, i-propylamine, n-butylamine, sec-butylamine, tert-butylamine, substituted amines having 2 to about 20 C atoms, such as 2- (N, N-dimethylamino) -1 - aminoethane.

Suitable diamines have, for example, two primary, two secondary, two tertiary or one primary and one secondary or one primary and one tertiary or one secondary and one tertiary amino group. Examples of these are diaminoethane, the isomeric diaminopropanes, the isomeric diaminobutanes, the isomeric diaminohexanes, piperazine, 2,5-dimethylpiperazine, amino-3-aminomethyl-3,5,5-trimethylcyclohexane (isophoronediamine, IPDA), 4,4'-diamino dicyclohexylmethane, 1,4-diaminocyclohexane, aminoethylethanolamine, hydrazine, hydrazine hydrate or triamines, such as the diethylenetriamine or 1,8-diamino-4-aminomethyloctane or tertiary amines, such as triethylamine, tributylamine, dimethylbenzylamine, N-ethyl-, N-methyl- , N-cyclohexylmorpholine, dimethylcyclohexylamine, dimorpholinodiethyl ether, 1,4-diazabicyclo [2,2,2] octane, 1-azabicyclo [3,3,0] octane, N, N, N ', N'-tetramethylethylenediamine, N , N, N \ N ^C - Tetramethylbutanediamine, N, N, N ', N'-tetramethylhexanediamine-1,6, pentamethyldiethylenetriamine, tetramethyldiaminoethyl ether, bis (dimethylaminopropyl) urea, N, N'-dimethylpiperazine, 1, 2-dimethylimidazole or di (4- N, N-dimethylaminocyclohexyl) methane.

In the context of a further embodiment of the present invention, the ammonium perchlorate used is triethylammonium perchlorate or triisopropylammonium perchlorate or a mixture thereof.

It has been found in some cases to be advantageous if at least one alkyl radical of an ammonium perchlorate used according to the invention has a polar substituent. In principle, all polar substituents which, in the sense of the "functional groups" already mentioned above, improve or at least do not or only insignificantly impair the properties of the polymer composition with regard to antistatic behavior and heat stabilization during processing or long-term use are suitable. Corresponding polar substituents may 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. Within the scope of a further embodiment of the present invention, ammonium perchlorates are used as constituent of a polymer composition according to the invention which have at least one OH group.

Suitable for preparing such ammonium perchlorates are, for example, aliphatic amino alcohols containing 2 to about 40, preferably 6 to about 20, carbon atoms, for example ethanolamine, propanolamine, butanolamine, diethanolamine, dipropanolamine, dibutanolamine, triethanolamine, tripropanolamine, tributanolamine, tripentanolamine, 1 -Amino-3,3-dimethyl-pentan-5-ol, 2-aminohexane 2 ', 2 "-diethanolamine, 1-amino-2,5-dimethylcyclohexan-4-ol, 2-aminopropanol, 2-aminobutanol, 3-aminopropanol, 1-amino-2-propanol, 2-amino-2-methyl -l-propanol, 5-aminopentanol, 3-aminomethyl-3,5,5-trimethylcyclohexanol, 1-amino-1-cyclopentan-methanol, 2-amino-2-ethyl-1,3-propanediol, 2- (dimethyla- aminoethanol), aromatic-aliphatic or aromatic-cycloaliphatic amino alcohols having from 6 to about 20 carbon atoms, heterocyclic or isocyclic ring systems such as naphthalene or, in particular, benzene derivatives such as 2-aminobenzyl alcohol, 3- (hydroxymethyl) aniline, 2- as aromatic structures. Amino-3-phenyl-l-propanol, 2-amino-1-phenylethanol, 2-phenylglycinol or 2-amino-l-phenyl-l, 3-propanediol and mixtures of two or more such compounds are used.

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

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 constituent of the ammonium perchlorates which can be used according to the invention.

Suitable examples include hydroxyl-containing isocyanurates of the general formula I. CHYOH

(CH ₂ ) _n

HOYHC-

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 C atoms. Particularly preferred in the context of the present invention is the use of tris (hydroxymethyl) isocyanurate (THEIC) as a constituent of the stabilizer compositions according to the invention.

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

In a further embodiment of the present invention are as ammonium perchlorates, for example, 2-Ethylcarboxypyridiniumperchlorat, Formamidiniumperchlorat, the perchlorate salt of Trishydroxyethylisocyanurats, the perchlorate salt of 2- (diethylamino) ethanol, N- (2-hydroxyethyl) - moφholiniumperchlorat or Trioctylammoniumperchlorat or mixtures of two or more used.

A polymer composition according to the invention may in the context of the present invention, for example, only one of the above Ammoniumperch- lorate included. It is also possible within the scope of the present invention and also provided for a polymer composition according to the invention to comprise a mixture of two or more of the abovementioned ammonium perchlorates. It may be a mixture of two or more different types of ammonium perchlorates.

If a polymer composition according to the invention contains a mixture of two or more ammonium perchlorates, these two or more ammonium perchlorates may in principle be present in any desired ratio in the polymer composition according to the invention. It is preferred if at least one ammonium perchlorate has at least one alkyl radical having a polar substituent, for example an OH group. It is very particularly preferred if such an ammonium perchlorate makes up the largest amount of the ammonium perchlorates present in a polymer composition according to the invention in terms of quantity.

In the context of the present invention, a polymer composition according to the invention contains 0.01 to about 5% by weight, for example about 0.05 to about 3% by weight, of an organic ammonium salt of a perchlorate or a mixture of two, based on the total composition or more organic ammonium salts of perchlorates.

In addition to an ammonium perchlorate or a mixture of two or more ammonium perchlorates, a polymer composition according to the invention also contains at least one aminoalcohol having 2 to 12 C atoms in the alcohol radical, the melting point of the aminoalcohol being 80 ° C. or less.

It has been found in the context of the present invention that the use of amino alcohols having a carbon chain length in the alcohol radical in the range of 2-12 C-atoms advantageously alters the properties of a polymer composition according to the invention in an unpredictable manner, in that both the processing properties with regard to heat stability and the performance characteristics with regard to the fastest possible discharges of a commodity article that can be produced from a polymer composition according to the invention are the same to improve.

The alcohol radical can basically have an aliphatic, cycloaliphatic or aromatic skeleton. If an amino alcohol present in accordance with the invention has two or more alcohol radicals, the corresponding alcohol radicals can be, for example, exclusively aliphatic or exclusively cycloaliphatic or exclusively aromatic. However, it is also possible according to the invention that corresponding alcohol residues are of mixed construction. For example, it is possible for an aminoalcohol usable in the context of the present invention to comprise a mixture of aliphatic and cycloaliphatic or a mixture of aliphatic and aromatic or a mixture of cycloaliphatic and aromatic alcohol radicals. If an amino alcohol which can be used according to the invention has three alcohol radicals, these may be, for example, of aliphatic, cycloaliphatic and aromatic nature. If an alcohol radical is an aliphatic alcohol radical, this may be linear or branched, saturated or unsaturated, but preferably saturated. Cycloaliphatic and aromatic alcohol radicals can be mono- or polycyclic and optionally have substituents such as alkyl groups, halogens or, in addition to an existing OH group or in addition to the OH groups present, other polar substituents.

Suitable amino alcohols have alcohol radicals having from 2 to about 12 carbon atoms. Suitable examples are amino alcohol with alcohol radicals having 2, 3, 4, 5, 6, 7, 8, 9, 10 or 11 carbon atoms, for example from 2 to about 8 or 3 to about 6 carbon atoms.

It has further been found according to the invention that a combination of a perchlorate and an aminoalcohol having a number of 2 to 12 carbon atoms in the alcohol radical and a melting point of less than 80 ⁰ C in the processing of a polymer composition according to the invention allows an excellent distribution of the active ingredients within the polymer so that an unexpected increase in antistatic effect is achieved along with an improvement in heat stabilization.

For example, suitable amino alcohols may have a melting point of up to about 70 or up to about 60 or up to about 50 ° C. Also suitable in the context of the present invention are amino alcohols having a melting point below these values, for example amino alcohols having a melting point of up to about 40, up to about 30, up to about 20 or up to about 10 ^° C. or less, for example up to about 0, to about -10 or up to about -20 ^° C.

It has been found in the context of the present invention that it is advantageous if a polymer composition according to the invention contains at least one aminoalcohol which is an alkanolamine. Suitable amino alcohols are in principle aminomonoalcohols or aminodialcohols or aminotrialcohols or mixtures of two or more thereof, a polymer composition according to the invention being able to comprise, for example, an aminomonoalcohol or aminodialcohol or aminotrialcohol or a mixture of two or more thereof. In principle, in the context of the present invention all amino alcohols are suitable as constituents of a polymer composition according to the invention which fulfill the abovementioned conditions with regard to the number of carbon atoms in the alcohol radical and of the melting point. However, it has been shown in the present case that in some cases particularly advantageous effects can be achieved if the aminoalcohol is a monoaminoalcohol.

Suitable alkanolamines are, for example, ethanolamine, propanolamine, butanolamine, diethanolamine, dipropanolamine, dibutanolamine, triethanolamine, tri-n-propanolamine, triisopropanolamine, tributanolamine, tripentanolamine, 1-amino-3,3-dimethylpentan-5-ol, 2 -Aminohexane-2 ', 2 "-diethanolamine, 1-amino-2,5-dimethylcyclohexan-4-ol, 2-aminopropanol, 2-aminobutanol, 3-aminopropanol, 1-amino-2-propanol, 2-amino 2-methyl-1-propanol, 5-aminopentanol, 3-aminomethyl-3,5,5-trimethylcyclohexanol, 1-amino-1-cyclopentan-methanol, 2-amino-2-ethyl-1,3-propanediol, 2- (Dimethylaminoethoxy) ethanol, aromatic-aliphatic or aromatic-cycloaliphatic amino alcohols having 6 to about 20 C atoms, heterocyclic or isocyclic ring systems being used as aromatic structures, such as naphthalene or, in particular, benzene derivatives, such as 2-amino-1-phenylethanol, 2- Phenylglycinol or 2-amino-l-phenyl-l, 3-propanediol and mixtures of two or more such compounds are used.

A composition according to the invention contains the abovementioned organic ammonium perchlorates and the abovementioned amino alcohols, for example in a ratio of about 100: 1 to about 1: 100. It is particularly advantageous in the context of the present invention, if the content of amino alcohol is only slightly lower than the content of organic perchlorate, about the same size as the content of organic perchlorate or even slightly or significantly exceeds this content. This is reflected, for example, in appropriate Ratios of ammonium perchlorate to aminoalcohol of from about 2: 1 to about 1:30 or about, 5: 1 to about 1:20, or about 1: 1 to about 1:10.

In addition, a polymer composition of the invention may further contain one or more solvents.

For the purposes of the present invention, a "solvent" is understood as meaning a compound or a mixture of two or more compounds which is liquid within a certain temperature range and capable of producing an ammonium perchlorate present in a composition according to the invention or a mixture of two or more to dissolve such ammonium perchlorates. A suitable solvent in the context of the present invention is at least within a temperature range of about 45 to about 100 ⁰ C, preferably within a temperature range of about 30 to about 120 ⁰ C or within a temperature range of about 15 to about 150 ⁰ C and in particular within a Temperature range from about 0 to about 200 ⁰ C liquid. The term "within a temperature range of" refers in the context of the present text to the physical state of the solvent within the entire temperature range. This means, for example, that a solvent which should be liquid within a temperature range of about 0 to about 200 ° C, this state of aggregation over the entire temperature range has time, ie a melting point of less than 0 ⁰ C and a melting point of more than 200 ⁰ C shows.
