The kinetic behaviors of ethylene homo- olymerization and ethylene / l-hexene co-polymerization , catalyzed by the metallocene catalyst PS-DVB-MC in an 0.5 L stainless steel reactor , were studied. The effects of polymerization conditions on ethylene polymerization , such as concentration of catalyst , temperature of polymerization , pressure of ethylene , molar ratio of AI / Z r , etc ., were also investigated . Some leading results were as follows : the activity of the catalyst PS–DVB- MC for ethylene homo-polymerization was high ( 1.053 x 107 gPE / mol Zr·h ), but the molar ratio of AI / Zr was low ( 350:1 ); the catalytic ability for ethyleneα-olefin ( such as l hexene etc .) co-olymerization was great , and the corresponding activity come up to a maximum of 1.753 x 107 gPE / mol Zr·h while concenlration of l-hexene was 0.080 mol / L ; the molecular weight of polyethylene was about 180,000 , meanwhile the molecular weight distribution was narrow ( 2.19 ); the bulk density of polyethylene and ethylene / l-hexene co -polymer were 0.25 and 0.34 respectively .
