摘要： A process may include contacting ethylene monomer with Ziegler-Natta catalyst to form polyethylene. The Ziegler-Natta catalyst may be formed by contacting an alkyl magnesium compound with an alcohol and a metal reagent to form a blend, and contacting the blend with a first agent to form a solution of reaction product “A”. The solution of reaction product “A” may be contacted with a second agent to form a solid reaction product “B”, and the solid reaction product “B” may be contacted with a third agent to form a solid reaction product “C”. The solid reaction product “C” may be contacted with a fourth agent to form a solid reaction product “D”, and the solid reaction product “D” may be contacted with a fifth agent to form a catalyst component.

摘要： The present invention is directed to a process for the production of high density polyethylene by polymerisation of ethylene in the presence of a supported chromium oxide based catalyst which is modified with an organic compound comprising oxygen and a nitrogen atom which is selected from the group consisting of saturated heterocyclic organic compounds with a five or six membered ring, amino esters and amino alcohols. Such organic compounds allow manufacturing of HDPE with increases molecular weight distribution and increased molecular weight.

摘要： The present invention relates to novel methods for producing a bimodal or broad distribution of molecular weight polyolefin polymers using Cr/silica catalysts. In some aspects the methods utilize different pressures of hydrogen to tailor the properties of the polymer. In particular aspects, a method of preparing a polyolefin having a bimodal molecular weight distribution, comprising: (a) preparing a reaction mixture comprising a monomer, a catalyst, and an organic solvent; (b) heating the reaction mixture under a first set of reaction conditions to effect a first polymerization comprising the polymerization of a first fraction of the monomer; and (c) heating the reaction mixture under a second set of reaction conditions to effect a second polymerization comprising the polymerization of a second fraction of the monomer.
