    摘要： 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.

    摘要： The present invention has for its object to produce an isobutylene polymer having excellent performance characteristics by suppressing side reactions at the polymer growth termini during polymerization. The process of the present invention is to carry out a cationic polymerization of a monomer component containing isobutylene in the presence of a polymerization initiator, a catalyst, an ether compound, and an electron donor. Moreover, the process is to carry out a cationic polymerization of a monomer component containing isobutylene in the presence of a polymerization initiator, a catalyst, an ether compound, and an electron donor, and add a compound having the carbon-carbon unsaturated bond for introducing the carbon-carbon unsaturated bond into the polymer terminus.
