Abstract
The living isobutylene oligomerization initiated by diisobutylene hydr ochloride (1) or triisobutylene hydrochloride (2) in the presence of B Cl3 and benzyltriethylammonium tetrachloroborate has been studied by g as chromatography which allowed the detection of the individual oligom ers 2, 3, 4, etc. The reactions followed second-order kinetics, first- order with respect to initiator (1 or 2), first-order with respect to BCl3, and zeroth-order with respect to isobutylene. A kinetic model ha s been derived which explains these phenomena.
