Title:
POLYCARBONATE COPOLYMER
Document Type and Number:
WIPO Patent Application WO/2018/139136
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a polycarbonate resin which has excellent scratch resistance, shock resistance, thermal resistance, and amine resistance. The present invention is a polycarbonate copolymer comprising, as main structural units: (A) a structural unit (A) represented by formula (1) [formula 1] (in formula (1), R1 and R2 are each independently a hydrogen atom, a hydrocarbon group having 1 to 9 carbon atoms which may include an aromatic group, or a halogen atom); (B) a structural unit (B) represented by formula (2) [formula 2] (in formula (2), R3 and R4 are each independently an alkyl group having 1 to 6 carbon atoms or a halogen atom. X is a single bond, a substituted or unsubstituted alkylene group, a substituted or unsubstituted alkanediyl group, a sulfur atom, or an oxygen atom); and (C) a structural unit (C) represented by formula (3) [formula 3] (in formula (3), W is a single bond, a substituted or unsubstituted alkylene group, a substituted or unsubstituted alkanediyl group, a sulfur atom, or an oxygen atom). The proportions of the structural units (A), (B), and (C) to the total structural units are, respectively, 5 to 25 mol%, 35 to 60 mol%, and 30 to 50 mol%.
