Title:
POLYCARBONATE RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2024/024943
Kind Code:
A1
Abstract:
The present invention provides a polycarbonate resin composition which comprises a carbonate structural unit (X) that is derived from an aliphatic dihydroxy compound (1) represented by formula (1) and a carbonate structural unit (Y) that is derived from a dihydroxy compound (2) satisfying the requirement I described below; and this polycarbonate resin composition has a melting point peak temperature if the melting point peak temperature is determined by heating this polycarbonate resin composition at a heating rate of 20°C/min with use of a differential scanning calorimeter. Requirement I: A polycarbonate resin (2), which is obtained by polymerizing the dihydroxy compound (2) and a carbonate source by means of transesterification, has a melting point peak temperature if the melting point peak temperature is determined by heating this polycarbonate resin (2) at a heating rate of 20°C/min with use of a differential scanning calorimeter. (In formula (1), n represents an integer of 2 or more.)
