Abstract: A process for producing organic polymers having silicon containing groups in high yields comprises hydrosilylating a polymer having unsaturated groups with a hydrosilicon compound. This process includes keeping the polymer and a solvent in an inert gas environment and introducing oxygen into the reactor just before starting the hydrosilylation reaction.

Abstract: The present invention provides a novel halogen-free solvent system which can produce a good isobutylene polymer and can be easily reused. A novel process for the production of an isobutylene polymer is provided which comprises using a hydrocarbon solvent having a boiling point of not lower than 105.degree. C. and a melting point of not higher than -90.degree. C. Heretofore, a solvent system containing a halogenated hydrocarbon such as methylene chloride has been used for the production of an isobutylene polymer. However, such a solvent system has a great adverse effect on the environment. Therefore, a non-halogenated solvent is desirable. The present invention is characterized by the use of a hydrocarbon solvent as a reaction solvent. The resulting polymer has good properties. Further, compounds which are produced as by-products during the reaction can be easily removed, enabling the recycling of the solvent used. Thus, the production cost can be reduced.

A process for the isolation of an isobutylene polymer includes a cationic polymerization reaction in a non-aqueous system in the presence of a catalyst MX.sub.n wherein M represents a metallic atom and X may be the same or different and represents a halogen atom or a monovalent hydrocarbon group. The process comprises conducting the cationic polymerization reaction, conducting a ligand exchange reaction of said catalyst, and then removing a component containing M.
