Thermoplastic composition comprising a compatibilized polyphenylene ether-polyamide base resin, one or more phosphorus compounds.

摘要

The present invention deals with a thermoplastic composition comprising (a) a compatibilized polyphenylene ether-polyamide base resin, and (b) 1-40 parts by weight per 100 parts by weight of polyphenylene ether present in (a) of one or more phosphorus compounds with the formula O=P-[Z]3, in which each Z can be the same or a different group and wherein each Z sterically hinders the reactivity of the O=P IDENTICAL moiety of the phosphorus compound. The composition may further comprise (c) 1-30 parts by weight per 100 parts by weight of polyamide present in (a) of one more compounds containing a bound triazine radical from the group of cyanuric acid and its derivatives. The use of special phosphorus compounds as described above makes it possible to manufacture the compositions in a simple way while obtaining stable compositions.
