Abstract
This paper reports a new kind catalytic system to produce linear low densit y polyethylene (LLDPE) from ethylene alone in a single reactor by combining the ability of Ti(OBu-n)(4)/AlEt3 to produce 1-butene with the ability of [Me(2)SiN(t)BuInd]ZrCl2/MAO to copolymerize ethylene with 1-butene. It was found that the dual-functional catalytic system has high activity and get t he good polymer with density ranging from 0.91-0.95 g/cm(3) in ethylene pol ymerization.
