摘要：
The synthesis and characterization of PFS-b-PMMA block copolymers, obtained by a sequential polymerization approach, is described. The poly(feffocenylsilane) (PFS) block was prepared by anionic polymerization of [1]dimethylsilafeffocenophane, and end-capped using 3-(tertbutyldimethylsiloxy)propyidimethylchlorosilane. Deprotection yielded a 3-hydroxypropyl-terminated PFS which was acylated with 2-bromoisobutyric anhydride. The 2-bromoisobutyryl end-functionalized PFS was used as a macroinitiator for controlled ATRP. Well-defined PFS-b-PMMA block copolymers with low polydispersities (M-w/M-n < 1.1) and controlled compositions were obtained.
