Patent ID: 7491346

Claim:
A polycarbonate resin comprising a repetitive unit represented by the following Formula (1) and a repetitive unit represented by the following Formula (2): [F1] (wherein R represents an alkyl group having 1 to 3 carbon atoms; n1 is an integer of 2 to 4; and n2 is an integer of 1 to 200), [F2] (wherein Ar represents a divalent aromatic group which comprises at least one of groups represented by the following Formula (3): [F3] [wherein R 1 and R 2 each represent independently a group selected from a trifluoromethyl group, a halogen atom, an alkyl group having 1 to 10 carbon atoms, an aryl group having 6 to 12 carbon atoms, a cycloalkyl group having 3 to 12 carbon atoms, an alkoxy group having 1 to 6 carbon atoms and an aryloxy group having 6 to 12 carbon atoms; and X represents a group selected from a single bond, —O—, —S—, —SO—, —SO 2 —, —CO—, —CR 3 R 4 — (wherein R 3 and R 4 each represent independently a group selected from a hydrogen atom, a trifluoromethyl group, a substituted or unsubstituted alkyl group having 1 to 10 carbon atoms and a substituted or unsubstituted aryl group having 6 to 12 carbon atoms), a substituted or unsubstituted cycloalkylidene group having 5 to 11 carbon atoms, a substituted or unsubstituted α,ω-alkylene group having 2 to 12 carbon atoms, a substituted or unsubstituted 9,9-fluorenylidene group, a substituted or unsubstituted arylene group having 6 to 12 carbon atoms, a divalent group derived from natural terpenes represented by the following formula: [F4] (wherein R 5 to R 7 represent the same groups as those represented by R 1 and R 2 ) and an alkylidenearylenealkylidene group having 8 to 16 carbon atoms represented by the following formula: [F5] (wherein R 8 to R 11 represent the same groups as those represented by R 1 and R 2 )], and wherein the group represented by formula (3) is (i) a combination of the group in which X is a single bond and the group in which X is a group other than a single bond, or (ii) a combination of the group in which all X are a single bond.
