Abstract

PURPOSE: To obtain the title catalyst by which polymers of uniform grain size and high bulk density are produced without requiring a process for removing the catalyst from the plymers, by reacting a specific org. Mg cpd. sol. in hydrocarbon media with Ti or V halide and bringing the resulting solid catalyst into contact with an organometallic cpd.
CONSTITUTION: A cpd. sol. in n-C7H16, etc. and represented by formula MgR1 pRq 2Xr.Ds is reacted with Ti or V halide, esp. TiCl4. The resulting solid catalyst is then brought into contact with an organometallic cpd. such as (C2H5)3 Al. In the above formula, R is a not less than 6 C hydrocarbon radical, X is an anionic radical contg. O, N or S, D is an organometallic cpd. of Al, Be, B, Zn, Si or Li, p=0W2, q=0W2, r=0W1, p+q+r=2, and 0.005≤s<0.1.
