Title:
POLYCARBONATE-BASED RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2023/157910
Kind Code:
A1
Abstract:
This polycarbonate-based resin composition has a specific viscosity average molecular weight (MvPC) and contains a polycarbonate-based resin (S) that contains: a polycarbonate-polyorganosiloxane copolymer (S-1) that includes a polycarbonate block (A-1) containing a repeating unit having a specific structure and a polyorganosiloxane block (A-2) having a specific average chain length and containing a repeating unit having a specific structure and a specific amount; and an aromatic polycarbonate-based resin (S-2) other than the polycarbonate-polyorganosiloxane copolymer (S-1). The difference between the viscosity average molecular weight (MvPC) of the polycarbonate-based resin (S) and the viscosity average molecular weight (MvSi) of the polycarbonate-polyorganosiloxane copolymer (S-1) (MvSi-MvPC) is -3100-6000.
