Title: Method of radiation polymerization and copolymerization of isobutylene by a cationic mechanism

Abstract: Method for the cationic polymerization of at least one olefinic monomer and more particularly the homopolymerization of a mono-olefinic monomer such as isobutylene and the copolymerization thereof with a di-olefinic monomer (diene) such as butadiene and optionally another mono-olefinic monomer in the presence of, as initiator of a halide of tetravalent vanadium, titanium and zirconium, an activator and under the influence of visible ultraviolet or infra-red light.
