ABSTRACT:
The specification discloses a polymer blend comprising 25 to 35% rubber dispersed in a laminar, network fashion in a rigid polymer phase. This is achieved by using a low molecular weight elastomer (70,000 to 100,000 weight average molecular weight) having 25 to 44% styrene and a melt flow rate of 8 to 15 grams per 10 minutes. This polymer blend is especially adapted for injection molding and products injection molded therefrom have a high gloss and excellent strength and toughness. The polymer blend is especially suited for injection molding and yields a high gloss, strong injection molded product.
