Web摘要： The cationic polymerization of isobutylene with weak Lewis acids, such as BBr3 and FeBr3, has been studied. These halides are unable to induce individually the polymerization in nonpolar solvents, such as heptane or toluene, or they only initiate the polymerization to low conversions in polar media, such as dichloromethane.
