Abstract:
The present disclosure provides high density polyethylene resins having good low temperature impact resistance. The resins are suitable for use in rotomolding application for large parts. The resin is a bi- or trimodal resin produced using solution phase polymerization in the presence of a single site catalyst.

Claim (Index 22):
A polyethylene resin comprising from 0.7 to 1.2 weight % of 1-octene and the balance ethylene, having a density from 0.948 to 0.953 g/cc, a melt index determined according to ASTM1238 under a load of 2.16 kg at a temperature of 190\u00b0 C. (I 2 ) from 1.0 to 1.5 g/10 minutes; a melt index determined according to ASTM1238 under a load of 21.6 kg at a temperature of 190\u00b0 C. (I 21 ) from 32 to 55 g/10 minutes; a weight average molecular weight (Mw) determined by gel permeation chromatography from 95,000 to 120,000; a number average molecular weight (Mn) determined by gel permeation chromatography (GPC) from 20,000 to 40,000; a z average molecular weight (Mz) from 240,000 to 360,000; an Mw/Mn from 2.7 to 4.3; an Mz/Mw from 2.5 to 3.5;\n and having a CBDI (50) from 80 to 95, the molecular weight distribution determined by GPC of said polymer being deconvoluted into at least three components comprising: \n from 20 to 40 weight % of a first component having a calculated weight average molecular weight (Mw) being from 170,000 to 265,000; a calculated number average molecular weight from 90,000 to 140,000; a z average molecular weight 390,000 to 520,000 and an estimated density from 0.921 to 0.930 g/cc; \n from 40 to 70 weight % of a second component having a calculated weight average molecular weight (Mw) being from 20,000 to 57,000; a calculated number average molecular weight (Mn) from 10,000 to 27,000; a z average molecular weight 30,000 to 72,000 and an estimated density from 0.948 to 0.953 g/cc, provided that the density difference between component two and component one is from 0.025 to 0.030 g/cc; and \n from 3 to 20 weight % of a third component having a calculated weight average molecular weight (Mw) being from 60,000 to 130,000; a calculated number average molecular weight from 30,000 to 65,000; a z average molecular weight 90,000 to 180,000 and an estimated density from 0.935 to 0.945 g/cc.
