摘要 |
Undesirable changes in shade brought about by low temperatures (Cold Stress Whitening) in impact-modified thermoplastic molding compositions F which comprise at least one elastomeric graft polymer A and at least one thermoplastic polymer B are reduced by adding from 10 to 200 ppm, based on the molding compositions F, of at least one polyorganosiloxane S to the impact-modified thermoplastic molding composition F.
