摘要：

Addition of equimolar amounts of (eta(5)-C(5)Me(5))TiMe(3) and B(C6F5)(3) to solutions of isobutylene or isobutylene and isoprene (99:1 molar ratio) in toluene at -78 degrees C results in polymerization To give, respectively, isobutylene homopolymer with a high weight average molecular mass of similar to 5 x 10(5) and a narrow polydispersity (2.1), or an isobutylene-isoprene copolymer exhibiting a composition, a molecular mass distribution and H-1 and C-13 NMR spectra identical to those of a sample of commercial butyl rubber.
