    摘要: A composition containing a graft polymer based on acrylonitrile/ethylene propylene rubber/styrene (AES) and an additive is disclosed. The additive is one which increases the “Δsoft phase” of the composition making it possible to produce moldings with improved toughness at low temperatures, without substantially changing the melt volume rate.
