Abstract
The present invention relates to a polycarbonate-polyorganosiloxane copolymer including: a polycarbonate block (A-1) including a structural unit represented by the following formula (II); and a polyorganosiloxane block (A-2) including a repeating unit represented by the following formula (III), wherein the ratio of the structural unit represented by the formula (II) to the total of the structural unit represented by the formula (II) and the repeating unit represented by the formula (III) is 60 mass % or more, and a resin composition including the polycarbonate-polyorganosiloxane copolymer and a molded article thereof.
Claims13
