ABSTRACT:
The synthesis and characterization of novel multi-arm star polymers comprising polyisobutylene arms connected to a well-defined, siloxane core are described. The synthesis has been achieved by hydrosilating olefin-capped (e.g., allyl- or isopropenyl-terminated) polyisobutylene with siloxanes carrying a plurality of Si--H groups.
