Abstract
A process for the production of poly-n-butenes having a reduced content of isobutylene from isobutylene-containing C.sub.4 feed stocks in a molecular weight range between 1,300 and 350 under controlled polymerization conditions, at a temperature range of 65.degree.-115.degree.F and in the presence of promoted aluminum chloride in quantity of 0.02 to 0.1% by weight based on total hydrocarbon feed, and the poly-n-butene products so produced.
Claims5
The method of forming liquid polybutene polymer having a molecular weight in the range of 335 to 1,300 and having an increased poly-n-butene content, said method comprising polymerizing a C.sub.3 - C.sub.5 liquified feed gas containing at least 3% of butylenes comprised of 10 to 70% isobutylenes and 10 to 30% n-butenes, at a temperature in the range of 65.degree. to 115.degree. F in the presence of from about 0.035 to 0.1% by weight of said hydrocarbon of dry aluminum chloride particles promoted with a minor quantity of a promoter.
