POLYCARBONATE RESIN COMPOSITION AND MOLDED PRODUCT THEREOF

WIPO Patent Application WO/2018/159781

A1

A polycarbonate resin composition comprising a styrene-based resin (C) blended in a polycarbonate resin (S) fulfilling conditions (1) and (2). The polycarbonate resin composition is characterized by the ratio of polycarbonate resin (S), relative to the total amount 100% by mass of the polycarbonate resin (S) and the styrene-based resin, being 50%–99% by mass. (1) Includes a polycarbonate–polyorganosiloxane copolymer (A) and an aromatic polycarbonate resin (B) other than the polycarbonate–polyorganosiloxane copolymer (A), said polycarbonate–polyorganosiloxane copolymer (A) including a polycarbonate block (A–1) comprising a specified repeating unit and a polyorganosiloxane block (A–2) including a prescribed repeating unit. (2) Has a structure having therein: a domain (d–1) including the polyorganosiloxane block (A–2), present in a matrix having the aromatic polycarbonate resin (B) as the main component thereof; and a domain (d–2) including at least one selected from a block derived from the aromatic polycarbonate resin (B) and the polycarbonate block (A–1), present inside the domain (d–1).
