Abstract
Tris-organophosphite compositions are provided having an improved hydrolytic stability, comprising (1) a tris-organophosphite of the formula: ##STR1## wherein: R.sub.1, R.sub.2 and R.sub.3 are selected from the group consisting of alkyl, alkenyl, aryl, alkylaryl and aralkyl groups together aggregating at least fourteen carbon atoms up to about sixty carbon atoms; and (2) a long-chain aliphatic amine in an amount to improve the hydrolytic stability of the phosphite and having the formula: ##STR2## wherein: R.sub.4, R.sub.5 and R.sub.6 are selected from the group consisting of hydrogen; aliphatic (including alkyl and alkenyl) groups having from one to about thirty-six carbon atoms; and hydroxyalkyl having from two to about six carbon atoms; one of R.sub.4, R.sub.5 and R.sub.6 is an aliphatic group having at least ten carbon atoms, and the remaining of R.sub.4, R.sub.5 and R.sub.6 are selected from hydrogen, alkyl having from one to four carbon atoms and hydroxyalkyl; and preferably at least one of R.sub.4, R.sub.5 and R.sub.6 is hydroxyalkyl.
