摘要
Provided is a polycarbonate-polyorganosiloxane copolymer including polycarbonate blocks (A-1) each formed of a specific repeating unit and polyorganosiloxane blocks (A-2) each containing a specific repeating unit, wherein the polycarbonate-polyorganosiloxane copolymer satisfies the following expression (F1a):15≤wM1 (F1a)wherein wM1 represents the average content of the polyorganosiloxane blocks (A-2) in polycarbonate-polyorganosiloxane copolymers each having a molecular weight determined by using a polycarbonate as a conversion reference of from 56,000 or more to 200,000 or less among polycarbonate-polyorganosiloxane copolymers obtained through the separation of the polycarbonate-polyorganosiloxane copolymer by gel permeation chromatography.
