Abstract:The binary random in-chain silyl-hydride multi-functionalized poly(styrene/butadiene/isoprene and dimethyl[4-(1-phenylvinyl) phenyl]silane) (PS-DPESiH, PB-DPESiH, PI-DPESiH) copolymers were successfully synthesized. These functionalized copolymers were prepared in hexane with n-BuLi as the initiator at 50 degrees C for 4 h. The silyl-hydride group; were introduced into polymer backbones quantitatively by living anionic polymerization. The copolymers were determined through H-1 NMR, size exclusion chromatography (SEC) and differential scanning calorimetry (DSC) techniques, while the number of silyl-hydride groups was calculated and discussed.
