PROCESS FOR POLYMERIZING ALPHA-OLEFINS |
摘要 |
A process for polymerizing an alpha-olefin using either a catalyst formed by contacting a highly active solid titanium catalyst component, an organometallic compound of a metal of Group 1 to 3 of the periodic table, an organic halogen compound or a transition metal compound, and an organosilicon compound or a sterically hindered amine in an inert medium in the absence of an alpha olefin, or a catalyst prepared by preliminarily polymerizing an alpha olefin in the presence of a catalyst comprising the above four catalyst components, provided that the last one is an optional component. This process achieves the industrially advantage that the catalysts are highly active, and give a polymer having excellent stereoregularity.
