Title:
POLYCARBONATE RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2023/074738
Kind Code:
A1
Abstract:
The present invention provides a polycarbonate resin composition which comprises a carbonate structural unit (X) that is derived from an aromatic dihydroxy compound represented by formula (1), a carbonate structural unit (Y) that is derived from an aromatic dihydroxy compound represented by formula (2) and a carbonate structural unit (Z) that is derived from an aromatic dihydroxy compound represented by formula (3). The content of the carbonate structural unit (Y) relative to the carbonate structural unit (X) is 0.65 or more in terms of the molar ratio; and the content of the carbonate structural unit (Y) in 100 mol% of all carbonate structural units in the polycarbonate rein composition is 49 mol% or less. (In the formulae, each of R1 and R2 represents a hydrogen atom, a substituted or unsubstituted alkyl group having 1 to 20 carbon atoms, or a substituted or unsubstituted aryl group; and R1 and R2 may combine with each other to form a ring.) (In the formulae, W represents -O-, -S-, -SO2-, -CR3R4-; each of R3 and R4 represents a hydrogen atom, a substituted or unsubstituted alkyl group having 1 to 20 carbon atoms, or a substituted or unsubstituted aryl group; and R3 and R4 may combine with each other to form a ring.)
