<p>2,6-di-t-butyl-4-substituted phenyl bis(3,6-di-t-butyl -2-naphthyl)phosphites, readily prepared by reacting together a phosphorodichloridite of a 4-substituted-2,6-di-t-butylphenol and a sodium salt of 3,6-di-t-butyl -2-naphthol, to form antioxidant and ultraviolet stabilizers that form particularly effective combinations with hydroxyphenylalkyleneyl isocyanurates to provide enhanced oven aging properties to organic materials subject to attack by heat and oxygen.</p> |
