METHOD FOR PRODUCING POLY-N-BUTYLENES FROM A BUTYLENE CUT BY MEANS OF ALUMINUM CHLORIDE CATALYSTS.

摘要

Poly-n-butene is prepared from a mixed C4 hydrocarbon feedstream containing less than about 5 wt.% isobutylene using an AlCl3-HCl catalyst system wherein the HCl is introduced separately into the feedstream to form organochloride in the feedstream. Polymer product having a very narrow molecular weight distribution is obtained over the Mn range of 300 to 900.
