Abstract: This paper reports a new kind catalytic system to produce linear low density 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 [Me2SiNt BuInd]ZrCl2/MAOto copolymerize ethylene with 1 butene. It was found that the dual functional catalytic system has high activity and get the good polymer with density ranging from 0.91-0.95 g/cm3 in ethylene polymerization.

Key words: Dual functional catalytic system, Linear low density polyethylene(LLDPE)
