Abstract:
1. A catalyst for olefin polymerization, comprising: a solid catalyst component comprising: [A] a solid component having 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: wherein Mt is a metal atom belonging to Groups 1-3 of the Periodic Table, R 1 and R 2 are 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 compound, an alcohol compound and a siloxane compound.
