Document Type and Number:

Japanese Patent JP4308440

Kind Code:

B2

Abstract:

The present invention relates to a process for preparing a catalyst, a novel polymer and a process for preparing the polymer. In particular, the invention provides a process for preparing a homopolymer and/or copolymer having an irregular particle structure and a melt flow index (MFR 190/15) of from 1.3 g/10 min to 10 g/10 min, a molecular weight distribution M_w/M_nof from 3 to 30, a bulk density of from 0.05 g/cc to 0.4 g/cc and a particle size of from 5 mum to 300 mum, which comprises polymerizing the monomers in the presence of a mixed catalyst comprising a titanium component and an organic aluminum compound and the presence of a molar mass regulator.
