1. A process comprising:
providing a propylene-derived olefin mixture to a reactor; and
reacting the propylene-derived olefin mixture under suitable conditions to form a mixture of oligomers in the presence of a catalyst comprising alkyl aluminum halide complex;
wherein the propylene-derived olefin mixture comprises propylene dimer, propylene trimer, propylene tetramer, or any mixture thereof and wherein at least about 60% by weight of the total amount of propylene dimer, propylene trimer, and propylene tetramer in the propylene-derived olefin mixture is reacted to form the mixture of oligomers and wherein the formed mixture of oligomers comprises propylene oligomers comprising at least 15 carbons atoms.
