摘要： A halogen-containing polycarbonate resin is formed by co-polymerizing:(a) 15 to 55 parts by weight of a polycarbonate oligomer with terminal chloroformate groups, having a number average molecular weight of 500 to 10,000 and containing no aromatic halogen or less than 4% by weight of aromatic halogen,(b) 20 to 80 parts by weight of a halogen-containing polycarbonate oligomer with terminal chloroformate groups, having a number average molecular weight of 1,000 to 10,000 and containing 6 to 30% by weight aromatic halogen, and(c) 5 to 25 parts by weight of bisphenol A.
