ABSTRACT:
Carbonate polymers (PC) such as randomly branched carbonate polymers, linear carbonate polymers and blends thereof are blended with acrylonitrile-ethylene-propylene-diene rubber (EPDM)-styrene copolymers and MBS as impact modifiers. The MBS impact modifiers are located at the PC and the acrylonitrile-ethylene-propylene-diene rubber (EPDM)-styrene copolymer interphases or in the PC phase so that higher melt elasticity and better blow molding is achieved.
