- W2394243350 abstract "In this paper, the reaction conditions of ethylene polymerization with the metallocene catalyst and catalytic performance were researched.Under the optimium conditions,the polymerization product was obtained with the zirconocene metal catalyst and compared with the product of the Jilin Petrochemical Company.The optimium conditions are as follows: the [Cat]/[Al] mole ratio is about 1 500, the main catalyst concentration is about 1.5×10-4 mol/L, the temperature is 60 ℃. The catalyst activity can reached up to 106 g PE/ (mol cat h) under this reaction conditions. From the comparison results of the physical properties, thermal properties, the relative degree of branching and molecular weight distribution analysis, It's concluded that the polymerization production by the zirconocene metal catalyst has the basic nature of the Jilin Petrochemical polyethylene products. And the polymerization production has the virtues of branched-chain evenly distributed, more narrow molecular weight distribution. The role and mechanism of the main catalyst and the co-catalyst for ethylene polymerization catalyst have also discussed in this paper." @default.
