Abstract
Improved thermoplastic compositions based on compatibilized blends of polyphenylene ether and polyamide are disclosed. These compositions contain radial block copolymers (such as those based on styrene/butadiene) having at least three polymer chains which often terminate with non-elastomeric segments.
Claims11
A thermoplastic composition consisting essentially of
- a) a polyphenylene ether resin;
- b) a polyamide resin;
- c) an effective amount of a compatibilizing agent for components a and b;
- d) 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
- e) an elastomeric material other than radial block copolymer d).
