    摘要： 2,6-Di-tertiary butyl phenyl pentaerythritol spiro bisphosphites are provided having the structure: ##STR1## wherein: R is alkyl having from one to six carbon atoms;R.sub.1 is methyl or ethyl;R.sub.2 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--O-- 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.
