摘要
Poly(aryl ether/thioether)-poly(aryl carbonate) block copolymers are prepared by reacting a poly(aryl carbonate) with a poly(aryl ether/thioether) having at least one electron-withdrawing group located in a position ortho or para to its ether/thioether linking group, in the presence of an exchange catalyst. At least a portion of the poly(aryl ether/thioether) blocks are joined to the poly(aryl carbonate) blocks through an ether/thioether oxygen or sulfur atom.
