Patent

CA 2035839

Ziegler polymerization of .alpha.-olefins is disclosed which is characterized by a solid catalyst component. The solid catalyst component, Component (A), comprises Sub-component (i) which is a solid catalyst component for Ziegler catalysts comprising Ti, Mg and a halogen; Sub-component (ii) which is a silicon compound having a plurality of a bond represented by a formula: Si-OR1 R1 m X n Si(OR2)4-n-m wherein R1 indicates a hydrocarbyl group of 1 to 8 carbon atoms, Sub-component (iii) which is a vinylsilane compound, and Sub-component (iii) which is an organometal compound of a metal of Groups I to IV of the Periodic Table. No need of an outside electron donor may be required, and the polymer produced is improved in its content of a "tacky" polymer.
