ABSTRACT:
A polycarbonate resin composition comprising a blend of (A) 1 to 90% by weight of a polycarbonate resin derived from 2,2-bis(4-hydroxyphenyl)propane and (B) 10 to 99% by weight of a polycarbonate resin derived from 1,1-bis(4-hydroxyphenyl)ethane, the amounts of (A) and (B) being based on the total weight of (A) and (B). The composition has improved impact strength and melt flowability while retaining the excellent transparency and heat deformation resistance of the polycarbonate resin (A).
