Title:

POLYCARBONATE RESIN COMPOSITION

Document Type and Number:

WIPO Patent Application WO/2023/149329

Kind Code:

A1

Abstract:

This polycarbonate resin composition includes a carbonate structural unit (X) derived from an aromatic dihydroxy compound represented by formula (1) and a carbonate structural unit (Y) derived from an aromatic dihydroxy compound represented by formula (2), and the contained amount of the carbonate structural unit (X) in 100 mol% of all carbonate structural units of the polycarbonate resin composition is 31.6 mol% or more. Alternatively, this polycarbonate resin composition includes the carbonate structural unit (X) derived from the aromatic dihydroxy compound represented by formula (1) and the carbonate structural unit (Y) derived from the aromatic dihydroxy compound represented by formula (2), and the contained mol ratio (Y)/(X) of the carbonate structural unit (Y) with respect to the carbonate structural unit (X) is 0.33-2.95.
