PROCESS FOR THE PREPARATION OF ETHYLENE (CO) POLYMERS

摘要

The homopolymerisation of ethylene or the copolymerisation of ethylene with other 1-olefins is carried out using a catalyst which comprises a trialkyl aluminium compound and the entire product from the reaction of a magnesium alkoxide compound with a tetravalent titanium compound and a halogen-containing organoaluminium compound. A polymer having coarse particles and high bulk density is obtained.
