发明名称 alpha, omega- FUNCTIONALIZED POLYOXYALKYLENE-SILOXANE POLYMERS AND COPOLYMERS MADE THEREFROM
摘要 An α,ω-functionalized polyoxyalkylene-siloxane polymer having the general structural Formula (I):;;provides improved hydrophilicity and hemocompatibility. The α,ω-functionalized polyoxyalkylene-siloxane polymer may be used to make various polycarbonate/α,ω-functionalized polyoxyalkylene-siloxane copolymers and polymer blends, as well as articles including such copolymers and blends.
