Abstract:
1. A process for the preparation of a polyethylene resin having a bimodal molecular weight distribution which comprises: (a) contacting ethylene monomer and a first co-reactant selected from the group consisting of hydrogen and a comonomer comprising a C (b) contacting ethylene monomer and a second co-reactant selected from the group consisting of hydrogen and a comonomer comprising a C (c) blending together said first and second polyethylenes to form a polyethylene resin comprising a blend of from 35 to 49 wt. % of a polyethylene fraction of high molecular weight and from 51 to 65 wt. % of a low molecular weight polyethylene fraction having a lower molecular weight than said high molecular weight polyethylene fraction, said high molecular weight polyethylene fraction comprising a linear low density polyethylene having a density of no more than 0.930 g/cm
