摘要： Polyethylene is often stabilized with the combination of a primary antioxidant (such as a hindered phenol, a hydroxylamine or a lactone) and a secondary antioxidant (such as a phosphonite, a monophosphite, or a diphosphite). The diphosphite additives are not completely compatible with “linear” polyethylene. This results in “blooming” of the diphosphite to the surface of the finished polyethylene part or polyethylene film. The use of a preblend of ethylene vinyl alcohol (EVOH) and diphosphite mitigates this problem.

摘要： Provided is a molded article in which the formation of depressions in a vapor deposited aluminum surface of the molded article caused by long-term exposure to high-temperature conditions is suppressed such that the vapor deposited aluminum surface has excellent external appearance that has not conventionally been achieved. A light reflective part includes a polyphenylene ether resin composition containing a polyphenylene ether (A) and 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide or a derivative thereof (B). The (A) component has a content of from 95 mass % to 99.95 mass % and the (B) component has a content of from 0.05 mass % to 5 mass % relative to 100 mass %, in total, of the (A) component and the (B) component.

摘要： A process for making a phosphorus-containing compound is disclosed. The process comprises contacting a compound of formula (A) wherein RA and RB are selected from optionally substituted aryl, aryloxy, alkyl and alkoxy groups or can be combined to form cyclic structures; and RC is methyl, ethyl, isopropyl, n-butyl, i-butyl, t-butyl, phenyl or benzyl; and a compound of formula (B) wherein R1-R4 are selected from optionally substituted aryl, aryloxy, alkyl and alkoxy groups. The phosphorus-containing compound can then be used as a flame retardants for polymers, especially for epoxy, polyurethane, thermosetting resins and thermoplastic polymers. Such flame retardant-containing polymers can be used to make protective coating formulations and ignition-resistant fabricated articles, such as electrical laminates, polyurethane foams, and various molded and/or foamed thermoplastic products.
