Polycarbonate resin composition

Abstract

PURPOSE: To obtain a composition having excellent physical characteristics, moldability as well as good adhesive property to metal, by blending a polycarbonate resin having a specific value of above of viscosity-average molecular weight with an aromatic polycarbonate oligomer having terminal alkyl ester groups. CONSTITUTION: A composition obtained by blending (A) a polycarbonate resin having ≥15,000, preferably 20,000W35,000 viscosity-average molecular weight with (B) an aromatic polycarbonate oligomer produced by using a terminator, expressed by formula I, II or III (X is COCl or COOH; Y is COO; n is 1W7; m is 1W8) and having average 2W15 constituent units expressed by formula IV (R is 1W10C straight-chain, branched chain or cyclic alkylidene, aryl- substituted alkylene, etc.; R 1 WR 4 are H, halogen or alkyl) and having ≤0.3 intrinsic viscosity or ≤15 average polymerization degree in an amount within the range of 1W60wt%, preferably 5W40wt%.
