Adjustion Of Microstructure Of The Copolynmer Of Styrene-Butadiene And Preparation Of Solution Polymerized Styrene-Butadiene Rubber (SSBR)

The research work in this paper is supported by China National Petroleum Corporation. Some theoretical and applied problems of anionic homo- and copolymer of styrene and butadiene have been studied in this paper. New polar modifiers are investigated to adjust microstructure of the copolymer of styrene-butadiene. By controlling microstructure of polymer with the modifiers, we can effectively synthesize low, medium, high vinyl solution polymerized styrene-butadiene rubber (SSBR) and hydrogenation polymer of medium vinyl SBS.Low, medium, high vinyl SSBR and SBS used for hydrogenation were synthesized, with n-BuLi as initiator, cyclohexane as solvent, and sodium dodecylbenzenesulfonate (SDBS)/tetrahydrofuran (THF) or...
