Summary:The present invention is related to synthesis of a novel series of phenolic phosphite compounds, and their use as an antioxidant for a polymer. A novel antioxidant has the advantages of both the hindered phenols and the phosphite antioxidant is prepared from phosphorus trichloride and 2,5-di-tert-butylhydroquinone, such as tetrakis-(2,5-di-tert-butyl-4-hydroxyphenyl)-2,5-di-tert-butyl-hydroquinonediyl diphosphite.
