titleOfInvention | Polycarbonate copolymer and molded body |
abstract | PROBLEM TO BE SOLVED: To provide a polycarbonate copolymer having excellent heat resistance and rigidity and improved hue. 5 to 95 mol% of a wholly aromatic dihydroxy component is represented by the following general formula [1], [Chemical 1] [Wherein, R 1 to R 4 each independently represent a hydrogen atom, a hydrocarbon group which may contain an aromatic group having 1 to 9 carbon atoms, or a halogen atom. Is a fluorene-based bisphenol represented by 95-5 mol% is the following general formula [2] [Chemical 2] [Wherein, R 5 to R 8 are each independently a hydrogen atom, a hydrocarbon group or a halogen atom which may contain an aromatic group having 1 to 9 carbon atoms, and W is a single bond, having 1 to 1 carbon atoms. A hydrocarbon group optionally containing 20 aromatic groups, an O, S, SO, SO 2 , CO or COO group. ] Wherein the b value of a solution obtained by dissolving 5 g of a powder of the polycarbonate copolymer in 50 ml of methylene chloride in a light-shielded state is 5.0 or less. Polycarbonate copolymer powder. [Selection figure] None |
