Olefin polymerization method |
| abstract |
There is provided a process for the production of an ethylene polymer in the presence of a Phillips-type chromium catalyst in a gas-phase polymerization reactor equipped with a circulating gas line comprising a heat-exchanger wherein a return to the polymerization reactor via the circulating gas line The cooled reactor gas is partially condensed and the amount of liquid in the returned reactor gas is from 0.5 wt.% To 10 wt.%, The polymerization is carried out at from 108 ° C to 125 ° C and the aluminum alkyl is added at a rate of 0.0025 mol ≪ / RTI > to 0.1 mole per mole of the polymer. |
