ABSTRACT:
Strengthened high impact resistant styrene polymers having improved physical-mechanical properties, particularly a high resilience at room temperature and at lower temperatures, and break elongation, containing as a dispersed phase an olefinic rubber, preferably an ethylene-propylene or an ethylene-propylene-diene rubber and a polyolefin. The amount of the polyolefin may be up to 15% by weight.
