As the upstream product of isobutene,the production of domestic methyl t-butyl ether(MTBE)is over capacitated.Thus,it is necessary to develop new techniques for high value-added polyisobutylene(PIB),a downstream product of isobutylene,which can promote the sustainable development of related industries and alleviate the pressure of overcapacity of MTBE.The physicochemical properties of various molecular weight PIB were reviewed.The technical research progress of PIB,the grades of industrialized products,the characteristics of products,and the applications of PIB with different molecular weights in various specialized fields of chemical industry were introduced.The main problems of domestic polyisobutylene industry were pointed out,and the future development directions of polyisobutylene were discussed.
