Abstract
Improved thermoplastic compositions are disclosed, comprising a polyphenylene ether resin capped with an epoxytriazine compound; a thermoplastic polyester; and a radial block copolymer which itself comprises at least about 60% by weight of a polymerized vinyl aromatic material, and about 5%-40% of a polymerized conjugated diene monomer.
Claims25
A thermoplastic composition comprising:
- a) polyphenylene ether capped with an epoxytriazine compound;
- b) thermoplastic polyester;
- c) a radial block copolymer which comprises about 60% to about 95% by weight polymerized vinyl aromatic material, and about 40% to about 5% by weight polymerized conjugated diene monomer, said copolymer having at least three polymer chains which form the radial configuration;
- and
- d) an elastomeric material.
