TH25632A - Solid titanium catalyst components Process for preparing such things Catalyst used to polymerization olefins With such thing And the process of polymerization olefin - Google Patents

Abstract

This invention Resulting in solid titanium catalyst components Which contains magnesium, titanium, halogen and electron carriers. Without removing titanium when washing with hexane at room temperature And a reduced proportion of titanium content At least 15% by weight when washed with 90 ํ ortho-dichlorobenzene. The catalyst component was prepared by a process where hard titanium (i) was without the removal of titanium when it was washed. Hexane at room temperature Contact with polar compounds containing 0.50 to 4.00 dipol momentum (Debye) to reduce titanium content. By at least 25% by weight by which solid titanium catalyst components can be prepared With at least 7 catalyst's body weight ratio to make the polymerization sun Containing catalyst This hard titanium It can be used for making (co) polymersunolifins with high activity to obtain high stereecoolary polyolefins. By reducing the amount of polyolefins With lower stereo recordlarity
