Abstract
In one embodiment the application pertains to a process which provides longer chain and less isomerized (more linear molecules). A propylene-derived olefin mixture is reacted under suitable conditions to form a mixture of oligomers in the presence of a catalyst comprising alkyl aluminum halide complex. A suitable alkyl aluminum halide complex comprises ethyl aluminum dichloride bis(2-chloroethyl) ether complex which may be used with a tert-butyl chloride or other initiator.
