摘要：
It is an object of the present invention to provide a polycarbonate-polydiorganosiloxane copolymer having improved transparency. The present invention is the polycarbonate-polydiorganosiloxane copolymer comprises a polycarbonate block and a polydiorganosiloxane block, wherein (i) the copolymer has an aggregation structure comprising a matrix of the polycarbonate and polydiorganosiloxane domains dispersed therein; (ii) the polydiorganosiloxane domains have an average size of 5 to 40 nm and a normalized dispersity of not more than 30%; and (iii) the total light transmittance is not less than 88%.
