HIGH-FLUIDITY POLYCARBONATE COPOLYMER, PROCESS FOR PRODUCTION HIGHLY POLYMERIZED AROMATIC POLYCARBONATE RESIN, AND AROMATIC POLYCARBONATE COMPOUND

摘要

PROBLEM TO BE SOLVED: To provide a novel polycarbonate copolymer having high fluidity in spite of a high molecular weight while keeping good original quality of a polycarbonate without using other resins, additives or the like.SOLUTION: A novel polycarbonate copolymer with high fluidity in spite of a high molecular weight is formed of a structural unit derived from an aliphatic diol compound having aliphatic hydrocarbon groups binding to the terminal hydroxy groups and a structural unit derived from an aromatic dihydroxy compound, and has a structure represented by the general formula (III), where the percentage of the structural unit derived from the aliphatic diol compound is 1-30 mol%. Also provided is a process of producing the same.SELECTED DRAWING: Figure 1
