PRODUCTION PROCESS OF OLEFIN POLYMERIZATION CATALYST COMPONENT, OF OLEFIN POLYMERIZATION CATALYST, AND OF OLEFIN POLYMER

摘要

A solid catalyst component for olefin polymerization, comprising titanium atoms, magnesium atoms, halogen atoms and hydrocarbyloxy groups, wherein the following filtrate contains titanium atoms in a concentration of 0.08 mg- Ti/ml-filtrate or lower, measured according to a method comprising the steps of (1) preparing a suspension of the solid catalyst component for olefin polymerization in heptane having a concentration of 0.1 g-solid catalyst component/ml-suspension, (2) heating the suspension at 70oC for 30 minutes under stirring, (3) filtering the suspension, thereby obtaining a filtrate, and (4) measuring a concentration of titanium atoms contained in the filtrate; and a production process of the solid catalyst component.
