ABSTRACT:
A catalyst for olefin polymerization, comprising:a solid catalyst component comprising[A] a solid component having substantially no hydroxyl group,[B] a compound of a transition metal selected from Groups 3-11 of the Periodic Table, and[C] a mixture of an activator compound (C-1) capable of reacting with the transition metal compound [B] to form a metal complex having catalytic activity and an organoaluminum compound (C-2); and[D] an organomagnesium compound soluble in a hydrocarbon solvent which is obtained by reacting (i) an organomagnesium compound represented by the general formula:in-line-formulae description="In-line Formulae" end="lead"?(Mt)α(Mg)β(R1)a(R2)bin-line-formulae description="In-line Formulae" end="tail"?wherein Mt is a metal atom belonging to Groups 1-3 of the Periodic Table, R1and R2are hydrocarbon groups of 2-20 carbon atoms, and α, β, a and b are numerals satisfying the following relationship: 0≦α, 0<β, 0≦a, 0<b, a+b>0, and rα+2β=a+b (where r is a valence of Mt) with (ii) a compound selected from an amine, an alcohol and a siloxane.
