Abstract

End-functionalized polymers have been widely studied and utilized as attractive functional polymers from the view points of both academic interests and industrial applications. In the rubber field, end-functional (modified) SBRs have become industrially popular during recent 10 years. It is because the compatibility of fillers with SBR becomes better by introducing appropriate functional group at polymer chain end and, therefore, the properties of vulcanized rubber are dramatically improved.<br>Recently, various well-defined end-functionalized polymers have been developed by means of living anionic polymerization using functionalized 1, 1-diphenylethylene (DPE) derivatives. DPE and its derivatives usually react efficiently with carbanionic species and highly reactive living anionic polymers in a monoaddition manner to afford 1:1 adducts quantitatively. Accordingly, they can be used both functional initiator and terminator based on such unique reactivities. Here, we report on the recent studies on the synthesis of well-defined end-functionalized polymers by means of living anionic polymerization using DPE derivatives. New systems for introducing definite number of functional groups at polymer chain end also will be described.
