Abstract

PURPOSE: To prepare a novel titled polymerization catalyst having high catalytic activity even at a low temperature and capable of eliminating an ash removal process, by combining a solid component obtained by calcining a Cr compound supported on an inorganic oxide carrier, and a specific organic Mg complex soluble in an inert hydrocarbon.
CONSTITUTION: An olefin (e.g. ethylene) is polymerized by using a catalyst prepared by compounding (A) a solid component prepared by calcining a chromium compound (e.g. chromium trioxide) supported on an inorganic oxide carrier, with (B) an organic Mg complex compound of formula [α, β are numbers larger than 0; p, q, r, s and t are ≥0, 0<(s+t)/(α+β)≤1.5, p+q+r+s+t=3α+2β; R1, R2 and R3 are 1W20C hydrocarbon; X and Y are OR4, OSiR5R6R7, NR8R9, or SR10 (R4WR10 are hydrocarbons)], soluble in an inert organic solvent.
