Title:
POLYCARBONATE RESIN COMPOSITION FOR OPTICAL MEMBER
Document Type and Number:
WIPO Patent Application WO/2020/183834
Kind Code:
A1
Abstract:
This resin composition contains, with respect to 100 parts by mass of an aromatic polycarbonate resin (A): 0.1-3 parts by mass of a polyoxytetramethylene glycol-based multidimensional polymer (B); and 0.005-0.4 parts by mass of a phosphorus stabilizer (C). The polycarbonate resin composition for an optical member is characterized in that the polyoxytetramethylene glycol-based multidimensional polymer (B) is a multidimensional polymer having a structure in which polyoxytetramethylene glycol-based random polymer components (B1) and (B3) are bonded via an alkylene diol (B2) and has a number average molecular weight (Mn) of 1,000-3,000.
