Polycarbonate copolymer |
| abstract |
PROBLEM TO BE SOLVED: To provide a polycarbonate copolymer having excellent heat resistance and rigidity and improved moldability by improving melt fluidity. SOLUTION: 5 to 95 mol% of a wholly aromatic dihydroxy component is a fluorene-based bisphenol represented by a specific formula, and 95 to 5 mol% is a polycarbonate copolymer composed of a dihydroxy component represented by a specific formula. When the glass transition temperature of the polycarbonate copolymer is Tg (° C.), T = Tg + 140 (° C.) The melt volume rate (MVR T ) at 20 ° C. and the specific viscosity (η sp ) at 20 ° C. in a solution of the polycarbonate copolymer dissolved in methylene chloride satisfy the following formula: Polycarbonate copolymer. 2.5 ≦ [log (MVR T ) +1.3] / η sp ≦ 10.0 [Selection figure] None |
