摘要：

Poly(dimethylsiloxane-2-ethyl-2-oxazoline) (PDMS-PEOX) diblock copolymers with narrow molecular weight distributions were prepared in two steps. The first involved living anionic ring-opening polymerization of hexamethyltrisiloxane and functional termination to afford monofunctional poly(dimethylsiloxane) oligomers with benzyl chloride endgroups. The second step involved the cationic ring-opening polymerization of 2-ethyl-2-oxazoline initiated by the activated halide on the monofunctional poly(dimethylsiloxane) oligomers. The well defined structure of these copolymers has allowed a fundamental investigation of structure-property relationships, which has included a study of solid, solution, and surface behaviour of these materials.
