First Claim
Patent Images
1. A thermoplastic composition having improved melt flow behavior, comprising:
- (a) a polyphenylene ether resin;
(b) a rubber-modified alkenyl aromatic resin;
(c) a low molecular weight copolymer of styrene and alpha methyl styrene in an amount which improves the melt flow of the combination of (a) and (b); and
(d) a thermoplastic elastomer in an amount sufficient to improve the impact strength of the combination of components (a), (b), and (c).

Abstract
The melt flow behavior of blends of polyphenylene ether resins and alkenyl aromatic resins such as high impact polystyrene can be markedly improved by incorporation therein of effective amounts of styrene-alpha methyl styrene copolymers.
