LiCB11(CH3)(12)-Catalyzed Radical Polymerization of Isobutylene: Highly Branched Polyisobutylene and an Isobutylene-Ethyl Acrylate Copolymer
In the presence of LiCB11Me12 catalyst and a nonoxidizing radical initiator, isobutylene undergoes radical chain polymerization in an inert solvent at ambient temperature and pressure to give a new highly branched form of polyisobutylene. Copolymerization with ethyl acrylate is also possible.
