Abstract

The invention relates to phosphites comprising substituted or unsubstituted tricyclodecylmethyl groups. The phosphites may also contain substituted and unsubstituted alcohols having about C6–C18 carbon atoms. The alcohol chain may be aliphatic, arylakyl and alkylaryl groups. The method of making of the phosphite composition is also described.
