THERMOPLASTIC POLYCARBONATE COMPOSITION

摘要

PURPOSE: Provided is a polycarbonate-based polymer alloy which has improved molding processability without impairing the mechanical properties of polymer alloys. CONSTITUTION: Resin compositions comprise (A) a polycarbonate resin and (B) a copolymer of (i) 0.1 to 10 % by weight of a methacrylic acid ester containing epoxy group, hydroxyl group or alkoxy group, (ii) 5 to 90 % by weight of a methacrylic acid ester other than the component (i), (iii) 5 to 70 % by weight of an aromatic vinyl compound, and (iv) 0 to 50 % by weight of other monomer copolymerizable with the components (i) to (iii). The molding processability of polycarbonate resins or blends of polycarbonate resin, aromatic vinyl copolymer and rubber-containing graft copolymer can be improved by the incorporation of the copolymer (B) without impairing the properties that the polycarbonate resins possess.
