Abstract: Terminally functionalized silicone polymers prepared using protected functionalized initiators and processes for preparing the same. The silicone polymers includes protected, functionalized silicone polymers, such as mono-functional, homotelechelic, heterotelechelic, macromonomer, and radial polymers. The protected functionalized polymers can be optionally deprotected to afford functionalized silicone polymers.

Abstract: Processes for the synthesis of star or multi-branched polymers and the resultant polymers. One or more alkadiene monomers are polymerized in the presence of suitable organometallic initiators and subsequently coupled to form star polymers. Prior to coupling, one or more alkenylsubstituted aromatic hydrocarbons are incorporated at the living ends of the polydienyl anions to provide increased linking efficiencies.
