Claims
- 1. A composition comprising from 5 to 95 wt % of a polyamide and, correspondingly, from 95 to 5 wt % of a carboxylated phenylene ether resin, and an impact modifier for polyphenylene ether resins, said carboxylated resin being the product of melt-mixing a mixture consisting essentially of 100 parts by weight phenylene ether resin and an ethylenically unsaturated carboxylic acid compound, said impact modifier comprising a hydrogenated styrene-butadiene-styrene block copolymer.
- 2. An improved process for preparing blends of polyamides and phenylene ether resins comprising the steps of
- (a) melt-mixing a mixture consisting essentially of 100 parts by weight of phenylene ether resin and an ethylenically unsaturated carboxylic compound to provide a carboxylated phenylene ether resin;
- (b) further melt processing said carboxylated phenylene ether resin in the presence of a polyamide and an impact modifier for polyphenylene ether resins, said impact modifier comprising a hydrogenated styrene-butadiene-styrene block copolymer
