POLYCARBONATE-POLYORGANOSILOXANE COPOLYMER AND METHOD FOR PRODUCING SAME

WIPO Patent Application WO/2015/087595

A1

A polycarbonate-polyorganosiloxane copolymer comprising a specific polycarbonate block unit (A) and a specific polyorganosiloxane block unit (B), wherein in a differential molecular-weight distribution curve obtained by measurements using gel permeation chromatography with polystyrene of the polyorganosiloxane block unit (B) as a conversion basis, the horizontal axis of the distribution curve being the logarithmic value log(M) of molecular weight M and the vertical axis thereof being dw/dlog(M) which is the concentration fraction w differentiated by the logarithmic value log(M) of molecular weight, (1) the value of dw/dlog(M) is the greatest in a range of 3.4≤log(M)≤4.0, and (2) in the differential molecular-weight distribution curve, an integrated value of the dw/dlog(M) value in a range of 4.0≤log(M)≤4.5 is 6 to 40% with respect to an integrated value of the dw/dlog(M) value in the entire range of log (M).
