According to new policy on the promotion of ethanol gasoline

the original domestic production capacity of about 18 million tons of methyl tertiary butyl ether (MTBE) is facing a life and death decision

and a large amount of downstream isobutylene resources need to find another way out. The development of high activity polyisobutene high-tech can alleviate the dual pressure of low utilization rate of isobutene and oil quality upgrade

and promote the sustainable development of carbon IV industry chain of refining and chemical enterprises. In this thesis

water (H2O)/dichloroethylaluminium (EADC)/2

2-dichlorodiethyl ether (CEE) was used as the initiating system to investigate the characteristics and laws of polymerization and to explore the method for preparing HRPIB with high conversion and high α-exo-olefin content.
