MOLDING COMPOSITIONS COMPRISING CARBONATE POLYMER, RUBBER MODIFIED VINYL AROMATIC-NITRILE GRAFT COPOLYMER AND METHYL(METH)ACRYLATE-BUTADIENE-STYRENE GRAFT COPOLYMER AND BLOW MOLDING AND THERMOFORMING PROCESSES USING SUCH COMPOSITIONS

摘要

Carbonate polymers (PC) such as randomly branched carbonate polymers, linear carbonate polymers and blends thereof are blended with rubber-modified vinyl aromatic-nitrile graft copolymers where the rubber is other than a conjugated diene and an MBS-type rubber is added as impact modifier. The MBS impact modifiers are located at the interface of the PC phase and the vinyl aromatic-nitrile copolymer phase or in the PC phase so that higher melt elasticity and better blow molding is achieved.
