OLEFIN POLYMERISATION PROCESS

摘要

A process for producing an olefin polymer in a slurry polymerisation process is disclosed, in which the process is operating at a temperature of 90° C. to 107° C. and utilising a chromium catalyst having an activity of at least 1,000 g polymer/g catalyst/hour on a support having a pore volume of at least 1.3 cm3/g, comprising adding to the polymerisation mixture from 0.1 to 100 ppm by weight of an anti-static agent, wherein the resulting polymer has a particle size distribution such that less than 8 vol %, preferably less than 5 Vol % of the polymer particles have an average diameter of 125 μm or less.
