A method includes transporting water containing chlorine dioxide, chlorine, chloramines, or hypochlorites through a pipe. The method includes forming a polyethylene resin using a catalyst, mixing the polyethylene resin with an antioxidant, wherein the antioxidant is a thioester, a hindered amine light stabilizer or 1,3,5-trimethyl-2,4,6-tris (3,5-di-tert-butyl-4-hydroxybenzyl) benzene to form a resin/antioxidant mixture, extruding pipe from the resin/antioxidant mixture, and flowing water containing chlorine dioxide, chlorine, chloramines, or hypochlorites through the pipe. An extruded article is adapted for use in containment and/or transport of water that contains chlorine dioxide, chlorine, chloramines, or hypochlorites. The extruded article includes a polyethylene resin and an antioxidant. The antioxidant is a thioester, a hindered amine light stabilizer or 1,3,5-trimethyl-2,4,6-tris (3,5-di-tert-butyl-4-hydroxybenzyl) benzene.

Chlorine-resistant polyethylene compound and articles made therefrom

A process includes combining a metallocene catalyzed polypropylene with a nucleator and a slip agent to form a composition, and forming a cast film from the composition. The slip agent may exhibit an increased slip bloom rate within the cast film relative to the slip bloom rate exhibited by the slip agent in an otherwise identical cast film in which the nucleator is not present in the cast film. The cast film may exhibit a coefficient of friction that is less than a coefficient of friction of an otherwise identical cast film in which the nucleator is not present in the cast film.

Use of nucleation to improve slip bloom in metallocene polypropylene resins

A blown film composition including a first high density polyethylene component and a second high density polyethylene component, wherein the blown film contains a mixture of three or more discrete molecular weight distributions, and wherein the second high density polyethylene component has at least one more discrete molecular weight distribution than the first high density polyethylene component.

Methods for improving multimodal polyethylene and films produced therefrom

kiA polyethylene resin having an a parameter of between 0.20 and 0.40 and an MWD of between 1 to 6.

Polyethyene and articles produced therefrom

Disclosed is a bimodal Ziegler-Natta catalyzed polyethylene, having a density of from 0.930 g/cc to 0.960 g/cc, and a molecular weight distribution of from 10 to 25, wherein an article formed therefrom has a PENT of at least 1500. Also disclosed is a method of preparing a tubular article including obtaining a bimodal polyethylene having a density of from 0.930 g/cc to 0.960 g/cc and a molecular weight distribution of from 10 to 25, and processing the polyethylene under conditions where a specific energy input (SEI) is less than 300 kW&#xb7;h/ton, and wherein the article has a PENT of at least 1500. Further disclosed is a method for controlling the degradation of polyethylene including polymerizing ethylene monomer, recovering polyethylene, extruding the polyethylene, and controlling the degradation of polyethylene by measuring the SEI to the extruder and adjusting throughput and/or gear suction pressure keep SEI less than 300 kW&#xb7;h/ton, and forming an article.

Bimodal pipe resin and products made therefrom

A blown film composition including an impact copolymer polypropylene component and a nucleating agent, wherein the blown film has improved processing and physical properties.

Use of nucleation in ICP resins

Polymer articles and processes of forming the same are described herein. The processes generally include providing an ethylene based polymer, blending the ethylene based polymer with a modifier to form modified polyethylene and forming the modified polyethylene into a polymer article, wherein the polymer article exhibits a haze that is at least about 10% less than a polymer article prepared with a similarly modified polyethylene.
