Abstract: Linear low-density polyethylene (LLDPE) was prepared byin situ polymerization using a dual-functional catalytic system containing Et(Ind)2ZrCl2/MAO and Ti(OnBu)4/AlEt3 used as co-polymerization catalyst and dimerization catalyst, respectively. The catalytic system showed high activity and the polymer with low melting point, narrow molecular weight distribution (MWD) and low crystallinity was produced.
