Self-extinguishing, thermoplastic polyphenylene ether/polyamide molding materials and their use for the production of moldings

Claim 1

A self-extinguishing, thermoplastic polyphenylene ether/polyamide molding material containing, as essential components, (A) from 10 to 90% by weight of component (A), which consists of (A1) from 70 to 99% by weight of a modified polyphenylene ether prepared from (a 1 ) 4.95-99.95% by weight of polyphenylene ether, (a 2 ) 0-90% by weight of a vinylaromatic polymer, (a 3 ) 0.05-10% by weight of (a 31 ) fumaric acid and/or (a 32 ) a maleimide of the formula I ##STR12## where R 1 , R 2 and R 3 are each hydrogen or an alkyl, alkoxy, cycloalkyl, alkenyl, aryl, arylene or alkylene group of 1 to 12 carbon atoms, and/or (a 33 ) a monomer containing amide groups and a polymerizable double bond and/or (a 34 ) a monomer containing lactam groups and a polymerizable double bond and/or (a 35 ) a half ester or half amide of an α,β-unsaturated dicarboxylic acid, (a 4 ) 0-80% by weight of further monomers capable of grafting and (a 5 ) 0-20% by weight of a free radical initiator, and (A2) from 1 to 30% by weight of a compound containing bound phosphorus, the percentages by weight being based on the total weight of components (A1) and (A2), (B) from 90 to 10% by weight of component (B), which consists of (B1) from 80 to 99% by weight of one or more polyamides and (B2) from 1 to 20% by weight of one or more compounds containing a triazine radical and from the group consisting of cyanuric acid and its derivatives, the percentages by weight being based on the total weight of components (B1) and (B2), (C) from 0 to 30% by weight of one or more impact-modifying rubbers and (D) from 0 to 60% by weight of one or more additives, the percentages by weight of components (A) to (D) summing to 100% by weight.
