Abstract
The present invention provides a method for producing high reactive polybutene (HRPB) in which carbon-carbon double bond is positioned at an end of polybutene. The method produces polybutene having 300.about.5000 of number average molecular weight (Mn) from (a) isobutene, (b) C4 hydrocarbon compounds derived from cracking of naphtha, and containing more than 10 weight % of isobutene, and (c) C4 hydrocarbon compounds derived from a refining process of crude oil or from catalytic cracking of heavy gas oil, and containing more than 10 weight % of isobutene by using catalyst comprising secondary alkylether, tertiary alcohol, and boron trifluoride.
