Title: POLYCARBONATE–POLYORGANOSILOXANE COPOLYMER, POLYCARBONATE RESIN COMPOSITION INCLUDING SAME, AND MOLDED PRODUCT THEREOF
Abstract:
A polycarbonate–polyorganosiloxane copolymer characterized by: including a polycarbonate block (A–1) comprising a prescribed repeating unit and a polyorganosiloxane block (A–2) including a prescribed repeating unit; and fulfilling formula (F1a). 15 ≤ wM1 (F1a) [In the formula, wM1 indicates the average amount of polyorganosiloxane blocks (A–2) contained in the polycarbonate–polyorganosiloxane copolymers having a molecular weight, using polycarbonate as a reference, of 56,000–200,000, among the polycarbonate–polyorganosiloxane copolymers obtained by separating the polycarbonate–polyorganosiloxane copolymers using gel permeation chromatography.]
