ABSTRACT:
Poly-n-butene is prepared from a mixed C.sub.4 hydrocarbon feedstream containing less than about 5 wt. % isobutylene using an AlCl.sub.3 -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 M.sub.n range of 300 to 900.
