    • 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.
    • 本发明的目的是通过在聚合过程中抑制聚合物生长末端的副反应来制备具有优异性能的异丁烯聚合物。 本发明的方法是在聚合引发剂,催化剂,醚化合物和电子给体的存在下进行含异丁烯的单体组分的阳离子聚合。 此外,该方法是在聚合引发剂,催化剂,醚化合物和电子给体的存在下进行含有异丁烯的单体组分的阳离子聚合,并加入具有碳 - 碳不饱和键的化合物用于引入 碳 - 碳不饱和键进入聚合物末端。
