A polyethylene resin having a multimodal molecular weight distribution comprising at least two polyethylene fractions A and B, fraction A being substantially free of comonomer and having a lower weight average molecular weight and a higher density than fraction B, each fraction prepared in different reactors of two reactors connected in series in the presence of a Ziegler-Natta catalyst system, the polyethylene resin having a density of from 0.950 to 0.965 g/cmand a melt index MI2 of from 0.5 to 5 g/10 min.

Bimodal polyethylene for injection stretch blow moulding applications

This invention covers injection stretch blow molded articles prepared from polyethylene resin having a bimodal molecular weight distribution (MWD), defined by the ratio of the weight average molecular weight (Mw) to the number average molecular weight (Mn), of from 2 to 20, comprising two polyethylene fractions A and B, fraction A being substantially free of comonomer and having a lower weight average molecular weight and a higher density than fraction B, each fraction prepared in different reactors of two reactors connected in series in the presence of a metallocene-containing catalyst system.

Injection stretch blow moulded articles

This invention is related to the preparation of polyethylene pipe resins suitable for transporting hot and cold water containing chlorine dioxide.

Resin and pipes for transporting water containing chlorine dioxide
