摘要： Bimodal polyethylene compositions and blow molded bottles made therefrom are provided. In at least one specific embodiment, the composition includes at least one high molecular weight polyethylene component having a molecular weight distribution (MWD) of about 6 to about 9, a short chain branch content of less than about 2 branches per 1,000 main chain carbons, and a Mz of about 1,100,000 or more. The composition also includes at least one low molecular weight polyethylene component where a ratio of weight average molecular weight of the high molecular weight polyethylene component to weight average molecular weight of the low molecular weight polyethylene component is about 20 or less. The composition has a density of about 0.94 g/cc or more, an ESCR of about 600 hours or more, and a percent die swell of about 70% or more.

摘要： Polyethylene resins having improved environmental stress crack resistance, stiffness and impact resistance is made by a process comprising feeding both a chromium oxide catalyst and a silyl chromium catalyst into a polymerization reactor. The chromium oxide catalyst and the silyl chromium catalyst are on separate supports. The chromium oxide catalyst is 25-50 weight percent and the silyl chromium catalyst is 50-75 weight percent of the total weight of catalyst. The catalysts may be added separately or as a single mixture.
