FLUIDITY IMPROVER FOR AROMATIC POLYCARBONATE RESIN, PROCESS FOR PRODUCING THE FLUIDITY IMPROVER FOR AROMATIC POLYCARBONATE RESIN, AROMATIC POLYCARBONATE RESIN COMPOSITION, AND MOLDED PRODUCT

摘要

A fluidity improver for a PC resin that improves the melt fluidity during molding without impairing the excellent properties (such as heat resistance and mechanical properties) of the PC resin, and also yields a molded product in which external appearance defects are unlikely. The fluidity improver for an aromatic polycarbonate resin according to the present invention is including a polymer (X) obtained by polymerizing 0.5 to 99.5 parts by mass of a monomer mixture (b) including 0.5 to 99.5% by mass of styrene (b1) and 0.5 to 99.5% by mass of phenyl (meth)acrylates (b2), in the presence of a polymer (A) obtained by polymerizing 0.5 to 99.5 parts by mass of a monomer mixture (a) containing 0.5 to 50% by mass of ±-methylstyrene (a1), 0.5 to 99% by mass of styrene (a2) and 0.5 to 99% by mass of phenyl (meth)acrylates (a3) (wherein the combined total of (a) and (b) is 100 parts by mass).
