Title:
POLYCARBONATE RESIN COMPOSITION AND OPTICAL LENS USING SAME
Document Type and Number:
WIPO Patent Application WO/2023/100777
Kind Code:
A1
Abstract:
According to the present invention, it is possible to provide a polycarbonate resin composition which includes a structural unit (A) derived from a monomer represented by general formula (i) and a structural unit (B) derived from a monomer represented by general formula (ii), and in which the structural unit (A) and the structural unit (B) are contained at a mass ratio of structural unit (A):structural unit (B) = 91:9 to 99:1. (In general formula (i), R represents a hydrogen atom or an alkyl group having 1-4 carbon atoms.) (In general formula (ii), R1, R2, R3, and R4 each independently represent a hydrogen atom or the like, and Y1 and Y2 each independently represent an alkylene group having 1-4 carbon atoms.)
