Abstract
The present invention relates to a polyamide composition comprising (A) polyamide, (B) polyphenylene ether, and (C) an ethylene-α-olefin copolymer prepared using a single site catalyst. The resin composition of the present invention can provide a polyamide composition having excellent impact resistance and excellent surface smoothness, and displaying only small dimensional changes after water absorption.
Claims24
A composition comprising:
- (A) 50 to 95% by weight of polyamide based on the total of components (A) and (B);
- (B) 50 to 5% by weight of polyphenylene ether based on the total of components (A) and (B);
- and
- (C) 1 to 30 parts by weight, based on 100 parts by weight of the total of components (A) and (B), of an ethylene-α-olefin copolymer prepared using a single site catalyst and/or an ethylene-α-olefin copolymer prepared using a single site catalyst and modified with one or more compounds selected from the group consisting of α,β-unsaturated dicarboxylic acid and derivatives thereof.
The composition according to claim1, wherein the composition contains at least one compatible agent selected from the group consisting of a copolymer comprising an aromatic vinyl compound and α,β-unsaturated dicarboxylic acid and/or derivatives thereof, maleic anhydride, fumaric acid, citric acid and malic acid.
