Abstract

PURPOSE: The titled catalyst that is composed of the solid component which is prepared by calcining silica, chromium trioxide and a liquid titanium compound under specific conditions and the other component of a specific magnesium compound and organoaluminum compound, thus showing high catalyst efficiency and giving polymer of high melt flowability.
CONSTITUTION: The polymerization of an olefin is carried out by use of a catalyst that is composed of (A) the solid component which is prepared by allowing a reaction mixture of (i) silica or silica-alumina carrier with (ii) a chromium trioxide with a water content of 0.05W2wt%, to react with (iii) a liquid titanium compound at -10W120°C and calcining them at 300W900°C in an oxygen atmosphere, and of (B) (iv) a hydrocarbon-soluble magnesium component of the formula[R1, R2 are 1W20 hydrocarbon; M is Al, B; X, Y are OR3 (R3 is H, 1W 20C hydrocarbon); α≥0, β>0; p,q,r,s≥0] and (v) an organoaluminum component of a reaction mixture between 1mol of trialkylaluminum and 0.1W1mol of 1W10C carbinol or 0.1W2mol of silanol.
