摘要
Pentaerythritol-spiro-bis-phosphite compositions are provided having an improved hydrolytic stability, comprising (1) a pentaerythritol-spiro-bis-phosphite of the formula: CHEM wherein: R1 and R2 are selected from the group consisting of alkyl and alkylaryl groups having at least fourteen carbon atoms up to about thirty-six carbon atoms; and (2) a long-chain aliphatic amine in an amount to improve the hydrolytic stability of the phosphite and having the formula: CHEM wherein: R3, R4, and R5 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 R3, R4 and R5 is an aliphatic group having at least fourteen carbon atoms, and the remaining of R3, R4 and R5 are selected from hydrogen, alkyl having from one to four carbon atoms and hydroxyalkyl; and preferably at least one of R3, R4 and R5 is hydroxyalkyl.
