Abstract
Abstract Thermoplastic molding materials which are free of cyanuric acid or cyanuric acid derivatives contain as essential components, (A) from 5 to 95% by weight of a toughened polyamide of a1) from 70 to 98% by weight, based on (A), of a polyamide and a2) from 2 to 30% by weight, based on (A), of an emulsion polymer whose particles do not have a hard outer shell, and (B) from 5 to 95% by weight of a functionalized polyphenylene ether.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
81 words
A thermoplastic molding material which is free of cyanuric acid or cyanuric acid derivatives and contains, as essential components, (A) from 5 to 95% by weight of a toughened polyamide of a1) from 70 to 98% by weight, based on (A), of a polyamide and a2) from 2 to 30% by weight, based on (A), of an emulsion polymer whose particles outer shell, have a Tg ≦20° C. and (B) from 5 to 95% by weight of a functionalized poly-phenylene ether.
Claim 2
Dependent Claim
81 words
A thermoplastic molding material which is free of cyanuric acid or cyanuric acid derivatives and contains, as essential components, (A) from 5 to 95% by weight of a toughened polyamide of a1) from 70 to 98% by weight, based on (A), of a polyamide and a2) from 2 to 30% by weight, based on (A), of an emulsion polymer whose particles outer shell, have a Tg ≦20° C. and (B) from 5 to 95% by weight of a functionalized poly-phenylene ether.
Claim 3
Dependent Claim
43 words
A molding material as claimed in claim 1, wherein a2) is an emulsion polymer whose particles consist of a core and one or more shells, wherein the core and the outer shell do not have a glass transition temperature higher than 0° C.
Claim 4
Dependent Claim
23 words
A molding material as claimed in claim 1, wherein the emulsion polymer a2) has one or more reactive groups in the outer shell.
Claim 5
Dependent Claim
41 words
A molding material as claimed in claim 3, wherein the reactive group in the emulsion polymer is introduced by polymerization of a functionalized monomer which contains a carboxyl, carboxylic ester, carboxamide, carboximide, anhydride, latent carboxyl, epoxy, urea, amino or urethane group.
Claim 6
Dependent Claim
108 words
A molding material as claimed in claim 1, wherein the functionalized polyphenylene ether (B) has been prepared by reacting b1) from 70 to 99.9% by weight of polyphenylene ether, b2) from 0 to 20% by weight of a vinylaromatic polymer, b3) from 0.1 to 30% by weight of an ethylenically unsaturated compound having one or more epoxy, amino, carboxyl, carboxylic anhydride, carboxylic ester, carboxamide or carboximide groups and b4) from 0 to 5% by weight of a free radical initiator, the percentages by weight being based on the sum of b1) to b4), in the course of from 0.2 to 15 minutes at from 240° to 360° C.
