Patent ID: 8642699

Claim:
A fluidity improver for an aromatic polycarbonate resin, comprising a polymer (X) obtained by polymerizing 0.5 to 99.5 parts by mass of a monomer mixture (b) comprising 0.5 to 99.5% by mass of styrene (b 1 ) and 0.5 to 99.5% by mass of phenyl (meth)acrylates (b 2 ), in presence of a polymer (A) obtained by polymerizing 0.5 to 99.5 parts by mass of a monomer mixture (a) comprising 0.5 to 50% by mass of α-methylstyrene (a 1 ), 0.5 to 99% by mass of styrene (a 2 ) and 0.5 to 99% by mass of phenyl (meth)acrylates (a 3 ), wherein a combined total of (a) and (b) is 100 parts by mass.
