Abstract:
A catalytic process for producing an olefin polymer, which comprises reacting together monomers of an olefin, a diolefin or a mixture thereof in the presence of a catalyst obtained by combining a solid catalyst component (A1) and at least one compound (B) selected from the group consisting of organoaluminum compounds and organoaluminumoxy compounds; wherein the solid catalyst component (A1) is obtained by contacting:(a) a carrier comprising carboxyl group-carrying polymer particles of spherical or elliptical shape having an average particle size of from about 1 to 200 &mgr;m and a standard deviation of particle size distribution of from about 1 to about 30 &mgr;m, (b) an organometallic compound of the number 1, 2 or 13 group of metals in the periodic table of elements, and (c) a transition metal compound of the number 4 group of metals in the periodic table of elements.
