ABSTRACT:
A catalyst component for polymerization of olefin, comprising a contact product of a component (A) which is a solid component containing titanium having at least one OR.sup.1 group (where R.sup.1 represents a hydrocarbon residue) and magnesium and a halogen as the essential components; a component (B) which is an acid halide compound; a component (C) which is a compound having an OR.sup.2 group (where R.sup.2 represents a hydrocarbon residue or hydrogen atom); and a component (D) which is a halide compound of silicon. When an olefin is polymerized by use of this as the transition metal component of a Ziegler type catalyst, an olefin polymer with high activity and high I.I and excellent polymer properties can be obtained.
