Patent number: 5811501Abstract: 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.Type: GrantFiled: June 27, 1996Date of Patent: September 22, 1998Assignee: Kanegafuchi Kagaku Kogyo Kabushiki KaishaInventors: Takeshi Chiba, Hiroshi Fujisawa, Yoshimichi Yamanaka, Yoshikuni Deguchi, Kazuya Yonezawa
