Carbon atoms polymerization process of 3 to 20 α- olefins 3~20 α- for olefin polymerization solid catalyst component, carbon atoms and polymerization catalyst containing the same

摘要

PURPOSE: To obtain the title catalytic component having high polymerization activity with high efficiency, suitable for producing olefin (co)polymers of high stereoregularity by mutual contact between each specific solid titanium catalytic component, organometallic compound catalytic component and transition metal compound catalytic component. ;CONSTITUTION: The objective catalytic component can be obtained by mutual contact between (A) a solid titanium catalytic component containing a compound having Ti, Mg, halogen and two or more ether links present through at least two atoms, (B) an organometallic compound catalytic component containing a metal selected from groups I to III metals (e.g. organoaluminum compound), and (C) a transition metal compound catalytic component containing e.g. titanium, soluble to inert organic solvents such as hexane. It is preferable that the respective amounts of the catalytic components to be used be as follows: A =0.1-20mmol per l of the liquid medium in terms of titanium; B=1-50mol per mol of Ti in the component A; and C =0.3-30mol.;COPYRIGHT: (C)1993,JPO&Japio
