Abstract: 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.

Abstract translation: 一种方法可以包括使乙烯单体与齐格勒 - 纳塔催化剂接触以形成聚乙烯。 齐格勒 - 纳塔催化剂可以通过使烷基镁化合物与醇和金属试剂接触来形成共混物，并使共混物与第一试剂接触以形成反应产物“A”的溶液。 反应产物“A”的溶液可与第二试剂接触以形成固体反应产物“B”，并且固体反应产物“B”可与第三试剂接触以形成固体反应产物“C”。 固体反应产物“C”可以与第四剂接触以形成固体反应产物“D”，并且固体反应产物“D”可与第五试剂接触以形成催化剂组分。
