Abstract

A new general anionic functionalization method (GFM) for preparing α-chain-end functionalized polymers utilizes the initiator formed from sec-butyllithium and dimethyl[4-(1-phenylvinyl)-phenyl]silane (DPESiH) followed by hydrosilation with substituted alkenes. α-(4-dimethylsilyl hydride)phenyl-functionalized polystyrene and poly(methyl methacrylate) were synthesized in quantitative yield by living anionic polymerization. These α-silyl hydride-functionalized polymers were further functionalized by reaction with tridecafluorooctene in the present of Karstedt's hydrosilation catalyst. These tridecafluorooctane-functionalized polymers were characterized by SEC, FTIR, 1H-, 13C- and 19F-NMR spectroscopy.
