Abstract
The ultraviolet light stability of polyphenylene ether resins and blends is improved by the addition of small amounts of certain 2-hydroxy-4-hydroxylated alkyl ether benzophenones and hindered amines in combination. The benzophenones are specifically characterized by an alkoxy substituent which contains one or more pendent hydroxy groups. Comparison with the closest prior art shows better UV performance. Plasticized, flame retardant and filled versions are also disclosed.
