【Abstract】 This article briefly introduces the mechanism of cationic polymerization of isobutene. The recent research status of Lewis initiators commonly used in cationic polymerization of isobutylene is discussed,such as boron-based,aluminum-based and titanium-based composite initiation systems. Then the new initiation system and new synthesis technology are described,which provides a new exploration field for the polymerization experimental process. Finally,the production status and future development prospects of highly active polyisobutylene are discussed.更多还原
