Abstract: Carbonate polymers (PC) such as randomly branched carbonate polymers and blends thereof with linear carbonate polymers are blended with ABS polymers and MBS polymers. The ABS polymers have greater than 18% acrylonitrile and the MBS polymers have an outer polymer shell made from alkyl (meth)acrylates. This locates the MBS rubber modifier in the PC phase and the PC/ABS interphase so that higher melt elasticity is achieved and the compositions are therefore useful in blow molding and thermoforming applications.

Abstract: Carbonate polymers (PC) such as randomly branched carbonate polymers, linear carbonate polymers and blends thereof are blended with ABS polymers and acrylonitrile-styrene-acrylate rubber (ASA) polymers as impact modifiers. The ABS polymers have greater than 18% acrylonitrile. The ASA impact modifier is in the PC and the ABS resin interphases so that higher melt elasticity is achieved.
