    摘要: Polymerization processes and polymers formed therefrom are described herein. Such processes generally include providing a catalyst system, introducing the catalyst system to a reaction zone, introducing 1-chlorobutane to the reaction zone, introducing an olefin monomer to the reaction zone, contacting the olefin monomer with the catalyst system in the presence of the 1-chlorobutane to form a polyolefin and withdrawing the polyolefin from the reaction zone. The catalyst system is generally formed from a process including contacting a magnesium dialkoxide compound with a first agent to form a first compound, contacting the first compound with a plurality of halogenating/titanating agents to form a reaction product and contacting the reaction product with an activating agent to form the catalyst system.

    摘要: Commonly used triethyl aluminum and tri-isobutyl aluminum cocatalysts may be replaced in olefin polymerizations with a cocatalyst conforming to the formula AlRz(Xz)nLzm wherein Rz may be a linear or branched organic moiety having at least 5 carbons and Xz may be a linear or branched organic moiety having at least 5 carbons or heteroatom substituted organic moiety or a heterocyclic moiety having at least 4 atoms and may be anionic (n=2) or dianionic (n=1). One Xz may also be hydrogen. The aluminum complex may also be in the form of an adduct complex where Lz may be a Lewis base and m=1−3. In the absence of a Lewis base, m=0.
