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 300~5000 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. |
