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.

摘要:
Flame retardancy of polyphenylene ether resins is increased by blending with the resin a flame retarding amount of a halophenyl hydrocarbyl ester. The ester is preferably the reaction production of a halogenated phenol, preferably a bromophenol, and a hydrocarbyl acid, acid chloride or acid anhydride. The polyphenylene ether resin may include homopolymers or copolymers of polyphenylene ethers or blends of polyphenylene ethers with vinyl aromatic resins such as styrene polymers and copolymers. The flame retarding halophenyl esters are also effective as processing aids in improving the flowability and moldability of the polyphenylene ether resins during melt processing.
