ABSTRACT:
The invention relates to polymer mixtures which comprise a polyphenylene ether, a polyamide and an agent to improve the impact resistance. The agent is an olefinic based polymer such as an ethylene-propylene copolymer or an ethylene-propylene-non-conjugated diene terpolymer, on which a vinylmonomer having a carboxylic acid group or a derivative thereof or on which a vinylmonomer having an epoxy group has been grafted or an alkylene-alkyl(meth)acrylate copolymer having an alkylene group with 2-6 carbon atoms and having an alkyl group with 1-8 carbon atoms or an alkylene-alkyl(meth)acrylate having a functional group, which functional group has been introduced either by a polymerisation reaction while forming a terpolymer or by a grafting reaction, the functional group being selected from carboxylic acid groups, acid anhydride groups, acid amide groups, imido groups, carboxylic acid ester groups, amino groups, hydroxyl groups or epoxy groups and in which the alkylene group of the alkylenealkyl(meth)acrylate comprises 2-6 carbon atoms and the alkyl group thereof comprises 1-8 carbon atoms.
