Claims
- 1. A polyphenylene ether resin composition comprising:
- (A) 100 parts by weight of a polyphenylene-ether-base resin composed of 100-60 wt. % of a polyphenylene ether resin and 0-40 wt. % of a polystyrene resin;
- (B) 1-40 parts by weight of a dicarboxylic acid ester copolymer obtained from a vinyl monomer and an unsaturated dicarboxylic acid ester as copolymerizable components wherein the proportion of the unsaturated dicarboxylic acid ester in the dicarboxylic acid ester copolymer (B) is in a range of from 10 wt. % to 80 wt. %, said dicarboxylic acid ester copolymer having a weight average molecular weight not greater than 60,000; and
- (C) 5-40 parts by weight of an A-B-A' block copolymer elastomer, in which A and A' represent polymerized, vinyl-substituted aromatic hydrocarbon blocks, respectively, and B represents a polymerized conjugated diene block or a hydrogenated, polymerized conjugated diene block.
- 2. A resin composition of claim 1 further comprising:
- (D) 5-40 parts of conductive carbon.
- 3. A polyphenylene ether resin composition comprising:
- (A) 100 parts by weight of a polyphenylene-ether-base resin composed of 100-60 wt. % of a polyphenylene ether resin and 0-40 wt. % of a polystyrene resin;
- (B) 1-40 parts by weight of a dicarboxylic acid ester copolymer obtained from a vinyl monomer and an unsaturated dicarboxylic acid ester as copolymerizable components wherein the proportion of the unsaturated dicarboxylic acid ester in the dicarboxylic acid ester copolymer (B) is in a range of from 10 wt. % to 80 wt. %, said dicarboxylic acid ester copolymer having a weight average molecular weight not greater than 60,000; and
- (C) 5-40 parts by weight of an A-B'-B" block copolymer elastomer, in which A represents a polymerized, vinyl-substituted aromatic hydrocarbon block, B' represents a random copolymer block of a vinyl aromatic compound and a conjugated diene, and B" represents a tapered block of the vinyl aromatic compound and the conjugated diene with the proportion of vinyl aromatic units increasing gradually toward one end of the tapered block; and the blocks have been hydrogenated subsequent to their connection in the order of A, B' and B".
- 4. A resin composition of claim 3 further comprising:
- (D) 5-40 parts of conductive carbon.
