Process for the preparation of ethylene (co)polymers |
摘要 |
For the homopolymerization of ethylene or for the copolymerization of ethylene with other 1-olefins, a catalyst is used which comprises a trialkylaluminum compound and the entire product from the reaction of a magnesium alkoxide which is dissolved, suspended or dispersed as a gel in an inert solvent, with a tetravalent transition-metal compound and an organoaluminum compound, washing with an inert solvent and reacting with a halogenated metal compound. A polymer having coarse particles and a high bulk density is obtained.
