POLYARYLCARDOSULFONE-POLYDIMETHYLSILOXANE-POLYETHER URETHANE SEGMENTED COPOLYMERS
聚酚酞醚砜-聚硅氧烷-聚醚氨酯多嵌段聚合物

Segmented copolymers have been prepared from dihydroxyl terminated polyaryl-cardosulfone oligomer and diisocynate terminated polydimethylsiloxane-polyether ure-thane block prepolymer through hydrogen transfer reaction. The main aspects of the reaction were investigated. The segmented copolymers obtained are of low crystallin-ity, and with twomicrophase morphology.
