    摘要: Polyolefins may be prepared using a cocatalyst conforming to the formula: AIRz(Xz)nLzm wherein Rz is a linear or branched organic moiety having at least 5 carbons and Xz is a linear or branched organic moiety having at least 5 carbons or a heterocyclic moiety having at least 4 atoms and can be anionic or di-anionic. The aluminum complex may also be in the form of an adduct complex where Lz is a Lewis base and m=1-3. The cocatalyst Rz components are selected such that they do not react with water under polymerization conditions to form a species that is highly soluble in the polymerization diluent. Use of the specified cocatalyst reduces fouling during metallocene-catalyzed runs and “post-metallocene hangover” when the same production equipment is transitioned to non-metallocene catalyst runs using catalysts such as chromium.

    摘要: Methods for improving heat transfer in polymerization processes are described herein. The methods generally include contacting olefin monomer with a catalyst system within a reaction zone to form particles having a first average particle size and altering the reaction zone to improve heat transfer and form polymer particles having a second average particle size. For example, the second average particle size may be larger than the first average particle size and the second particle size results in improved heat transfer over the first particle size.
