New Branched Polyisobutylenes and Butyl Rubbers by the Inimer Method
Contribution to Book
This paper reviews the synthesis of branched and hyperbranched polymers from an industrial point of view. The synthesis of branched polyisobutene and butyl rubber using the inimer method is presented. Branched copolymers were prepared in solution and bulk, using p-chloromethylstyrene (vinylbenzyl chloride) as inimer and MAO and diethylaluminum chloride as coinitiators. The polymers were characterized by SEC-viscometry.
