PROCESS FOR PRODUCING POLY(DIORGANOSILOXANE)/POLYCARBONATE BLOCK COPOLYMER

摘要

PROBLEM TO BE SOLVED: To provide a poly(diorganosiloxane)/polycarbonate block copolymer having better releasability and flowability, a rubber/glass transition transposed to a lower temperature, and an improved ESC behavior. SOLUTION: This process comprises producing the poly(diorganosiloxane)/polycarbonate block copolymer in a melted liquid using a specified transesterification catalyst. COPYRIGHT: (C)2009,JPO&INPIT
