Abstract: The instant invention provides a polyolefin composition and method of producing the same. The olefin polymerization process according to the present invention comprises contacting one or more olefinic monomers with a biphenylphenolic polymerization catalyst under polymerization conditions and in the presence of one or more treated aluminum-based scavengers in a polymerization reactor, wherein said one or more treated aluminum-based scavengers comprise the reaction product of an alkylaluminum or an aluminoxane specie with a compound of the general Formula (I): wherein X is O, N, or S and R is alkyl, aryl, heteroalkyl, heteroaryl, or hydrogen, wherein n=1 if X is O or S and n=1 if X is N, and wherein at least one R is not a hydrogen; Rn—X—H (I); thereby producing a polyolefin composition which comprises less than 50% of the oligomer level of a polyolefin composition produced in an olefin polymerization process in the presence of said one or more untreated aluminum-based scavengers.

Abstract: The present disclosure relates to a capped, multi- or dual-headed chain composition comprising derivatives of a strained olefin. The present disclosure further relates to a process for synthesizing the capped, multi- or dual-headed composition by using an organometallic compound and a co-catalyst in the presence of a catalyst precursor and a strained olefin. The present disclosure further relates to use of the compositions, as well as the process to make the same, in olefin polymerization.
