Bimodal polyethylene composition and articles made therefrom

Abstract

The invention involves a bimodal molecular weight distribution of polyethylene compounds and its products, such as high maximum blow moulding products and transportation and distribution pipes. The combination has a low molecular weight (LMW) ethylene homopolymer component of a homogeneous and high molecular weight (HMW) ethylene copolymer composition, LMW are characterized by their molecular weight distribution MWDL below about 8. The combination is characterized by bimodal molecular weight distribution and the ductile-brittle transition temperature lower than-20 ° c Tdb. In some cases related to the implementation, the HMW components is characterized by "reverse comonomer distribution".
