| Abstract: | Study of a new type gas phase ethylene polymerization catalyst fed in slurry was introduced.Physical properties of the catalyst were determined.Behaviour of the catalyst in polymerization,copolymerization and hydrogen regulation under different conditions was investigated.A suitable synthetic technique was selected,and the obtained catalyst was compared with imported catalysts.The obtained catalyst fed in slurry had good performance in polymerization,copolymerization and hydrogen regulation.Quantity of oligomer in product resin decreased(measured by hexane dissolubility).The catalyst is applicable for gas phase ethylene polymerization.A patent of invention for this catalyst has been applied. |
