Process for radiation polymerization and copolymerization of monomers with olefinic double bonds using metal halide catalysts

摘要

Process for polymerization and copolymerization of momo- olefinic monomers, such as isobutylene, either with one another or with dienes, catalyzed by tetravalent metal halides, and initiated or accelerated by the action of ultraviolet, visible or infrared light. The polymerization or copolymerization can be affected with or without solvent. Suitable solvents are aliphatic, aromatic or halogenated hydrocarbons. The polymerization is carried out at a temperature in a range of from about - 140° C. to about +30° C.
