摘要: Semi-crystalline, thermoplastic polyolefin block copolymers comprising: (A) A first polyolefin A block comprising isotactic poly(1-butene) (iPB); (B) A polyolefin B block comprising an ethylene and/or alpha-olefin/1-butene copolymer or terpolymer; and (C) A second polyolefin A block comprising isotactic poly(1-butene) (iPB); the A and B blocks bonded to one another to form a block copolymer in which the first and second polyolefin A blocks are joined to and separated by the polyolefin B block. In one embodiment the polyolefin block copolymer is a BAB block copolymer.

摘要: 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.

摘要: 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.
