Abstract

PURPOSE: To prepare a polyolefin having high bulk density, broad molecular weight distribution and improved melt properties, by carrying out the (co)polymerization of olefin in the presence of an organometallic compound and some specific solid components as a catalyst.
CONSTITUTION: Olefins are (co)polymerized by using a catalyst system comprising (A) a solid component prepared by pulverizing (a) a solid compound containing Mg and/or Ca, together with (b) an oxide of Al, the oxide treated with SO3 and/or the oxide treated with a halogenation agent, (c) an organic carboxylic acid RCOOH, a metal salt of an organic carboxylic acid RCOOM, an ester RCOOR', a ketone RCOR', an alcohol ROH, an ether ROR', an organic halide RX and/or a silicone expressed by the formula (R and R' and hydrocarbon; R" and R"' are H, alkyl, OH, etc.; M is IWIII group metal), and (d) a Ti compound and/or a V compound, and (B) an organometallic compound.
