Telechelic Star Poly(dimethylsiloxane)s of Highly Defined Structure

View publication

Abstract

The synthesis of amine telechelic, star-shaped poly(dimethylsiloxane)s of highly defined structure is reported. These polymers are prepared via utilization of a unique, blocked amine functional anionic initiator, which is soluble in nonpolar solvents. Once intitiated, a living anionic polymerization of D3is terminated with tetrachlorosilane to form the blocked, star polymer. After the unblocking, four-armed star, amine telechelic poly(dimethylsiloxane)s of controlled molecular weights, narrow molecular weight distributions, and theoretical functionalities are formed. © 1989, American Chemical Society.
