2,6-Di-tertiary butyl phenyl pentaerythritol spiro bis-phosphites are provided having the structure:
wherein:
R is alkyl having from one to six carbon atoms;
R is methyl or ethyl;
R2 is selected from the group consisting of alkyl having from one up to about eighteen carbon atoms; cycloalkyl having from three up to about twelve carbon atoms; and alkaryl and aryl having from six to about thirty carbon atoms; such groups substituted with from one to about four oxy ether-0- and/or carboxylic ester-COO-groups; the residue of a polyhydric alcohol having from two to about eighteen carbon atoms, and from two to about ten hydroxyl groups; and the residue of a polyphenol having from six to about eighteen carbon atoms and from two to about ten phenolic hydroxyl groups.
Stabilizer compositions are provided comprising a phenolic antioxidant and such phosphites as well as synthetic resin compositions having an enhanced resistance to deterioration by heat and/or light due to the presence of such a phosphite and/or stabilizer composition.
2,6-二叔丁基苯基季戊四醇螺双磷酸盐具有以下结构:
其中
R 是具有 1 至 6 个碳原子的烷基;
R 是甲基或乙基
R2 选自具有 1 至约 18 个碳原子的烷基;具有 3 至约 12 个碳原子的环烷基;具有 6 至约 30 个碳原子的烷芳基和芳基;这些基团被 1 至约 4 个氧醚-0-和/或羧酸酯-COO-基团取代;具有 2 至约 18 个碳原子和 2 至约 10 个羟基的多元醇的残余物;以及具有 6 至约 18 个碳原子和 2 至约 10 个酚类羟基的多元酚的残余物。
稳定剂组合物包括酚类抗氧化剂和此类亚磷酸酯以及合成树脂组合物,由于此类亚磷酸酯和/或稳定剂组合物的存在,合成树脂组合物的耐热和/或耐光性得到增强。
