Abstract
PURPOSE: To obtain the titled copolymer having a MW in the specified range, excellent chemical resistance and heat resistance and being capable of forming cast films having a strong self film-supporting property, by solution-polymerizing monomers by using polyphenylene oxide as a MW modifier.
CONSTITUTION: The titled block copolymer of the B-A-B type, represented by formula II, wherein R is a 1W5C alkylene, O, S, SO2 or CO, Y1W2are each H or a halogen, and m is 22W400, is obtained from (A) a polycarbonate block, wherein the number of repeating units m is 22W400, and (B) a polyoxyphenylene oxide block of formulaI, wherein Q1W4 are each H, a halogen, a hydrocarbyl and n is 2W200, wherein the number of repeating units n is 2W200. Component B is a MW modifier used in such an amount that the number of repeating units m of the polycarbonate resin falls within the range of 22W400, and it is necessary that the component is present in the block copolymer in an amount of 1W 70wt%, pref., 2W60wt%.
