A polycarbonate copolymer includes a repeating unit A represented by a formula (1) below, chain ends of the PC copolymer being terminated by a monovalent aromatic group or a monovalent fluorine-containing aliphatic group.
In the above formula (1), R1 is a hydrogen atom or an alkyl group having 1 to 2 carbon atoms; an average repeating number n is in a range from 6 to 40 and L is an integer of 1 to 4; and when an aromatic ring is substituted by two or more of R1 (L≥2), the two or more of R1 are the same or different from each other.
聚碳酸酯共聚物包括由下式(1)表示的重复单元 A,PC 共聚物的链端由一价芳香族基团或一价含氟脂肪族基团终止。
在上式(1)中,R1 是氢原子或具有 1 至 2 个碳原子的烷基;平均重复数 n 在 6 至 40 的范围内,L 是 1 至 4 的整数;当芳香环被两个或两个以上的 R1(L≥2)取代时,两个或两个以上的 R1 彼此相同或不同。
