Abstract

PURPOSE: A reaction product between a specific organomagnesium compound and a specific halide is brought into contact with a titanium compound or a mixture thereof with a vanadium compound and the resultant compound is used as a catalyst to produce a powdery polymer with a density lower than a specific value, narrow molecular weight distribution and high bulk density.
CONSTITUTION: A reaction product between an organomagnesium compound of MgMαRpXqDr [M is metallic atom of m valency of group IWIII in the periodic table; α, p, q, r are 0 or more number where p+q=mα+2, 0≤q/(α+1)≤1.5, 0≤r/(α+1)≤10; R is hydrocarbon group of 1W20 carbon atoms; X is H, anionic group containing O, N and S; D is electron-donating organic compound] and a mixture of halides of B, Si, Ge, Sn, Pb, P, As, Sb, Bi, Zn, Cd or Hg is brought into contact with a titanium compound or a mixture thereof with a vanadium compound to give a product. Then, the product is used as a polymerization catalyst and the copolymerization of ethylene and its comonomers are conducted at 0W100°C to produce the copolymer with a density of 0.945g/cm3.
