Abstract Recent developments are reviewed for the applications of reactions of polymeric organolithium compounds with epoxides and oxetane to obtain the corresponding ω-hydroxy chain-end functionalized polymers. State-of-the-art characterization methods for ω-functionalized polymers are also reviewed. Investigations of the usefulness of functionalization reactions of polymeric organolithium compounds with ethylene oxide, propylene oxide, 1-butene oxide, styrene oxide, oxetane, 3,4-epoxy-1-butene, 3-glycidoxypropyltrimethoxysilane and other epoxides are described. In general, these functionalization reactions are very efficient (> 90% yields of ω-hydroxy-functionalized polymers). The use of substituted epoxides is shown to provide an efficient methodology for attachment of a variety of groups at the polymer chain end.

Abstract A new general functionalization methodology (GFM) is applied to the synthesis of trimethoxysilyl-functionalized polymers. This GFM involves (a) the preparation of a well-defined polymeric organolithium compound (PLi) using alkyllithium-initiated anionic polymerization; (b) quantitative silyl hydride-functionalization of PLi with chlorodimethylsilane to form PSi(CH3)2H; (c) hydrosilation of PSi(CH3)2H with vinyltrimethoxysilane in the presence of Karstedt's catalyst. The desired PSi(OCH3)3 was obtained in > 80% yield. The product was characterized by SEC, 1H and 13C NMR and MALDI-TOF mass spectrometry.
