Abstract: 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.

Abstract: Molded articles are prepared from propylene-ethylene copolymers and exhibiting improved clarity and strength properties. Articles prepared include bottles and other thin-walled articles. The articles are prepared using an isotactic propylene-ethylene random copolymer resin having an ethylene content of from about 0.5 to about 3 percent by total weight of copolymer, with a xylene solubles content of less than about 1.5 percent. The injection molded article may exhibit less than about 20 percent haze, as determined by ASTM D1003, at a thickness of about 0.08 inch (2.03 mm). Articles may also be prepared from similar copolymers having an ethylene content greater than about 3 percent by total weight of copolymer, with a xylene solubles content of less than about 4 percent by total weight of copolymer. These articles may exhibit less than about 13 percent haze, as determined by ASTM D1003, at a thickness of about 0.08 inch (2.03 mm).
