Abstract

PURPOSE: To obtain the title high polymer having improved moldability, using a catalyst made by flending an organoaluminium compound with a sintered silica supported by a cr and a specific Zr compounds and by preparing the catalyst with maintaining polymerization activity at lowered sintering temperatures.
CONSTITUTION: An olefin is polymerized in the presence of a catalyst system consisting of A) a component obtained by sintering a) silica supported by b) a Cr compound (e.g., chromium oxide, etc.) and c) a zirconium compound shown by the formula I at 430W750°C, and B) a component of an organoaluminum compound (e.g., trialkylaluminum, etc.) shown by the formula II (R1 and R2 are 1W20C hydrocarbon; X is H, halogen, or 1W20C hydrocarbon), to give the desired high polymer.
