2,6-Di-tertiary butyl phenyl phosphites are provided having the structure:
wherein:
R is selected from the group consisting of hydrogen, methyl, ethyl, and (CH2)mCOOR, where R is selected from the group consisting of alkyl having from one up to about ten carbon atoms; cycloalkyl having from three up to about twelve carbon atoms; alkaryl and aryl having from six to about twelve carbon atoms; and m is a number within the range from 0 to 5;
R2 is selected from the group consisting of hydrogen, alkyl having from one to about twenty-two carbon atoms; cycloalkyl having from three up to about twelve carbon atoms; alkaryl and aryl having from six to about eighteen carbon atoms; the residue of a polyhydric alcohol having from two to about eighteen carbon atoms, and from two to three hydroxyl groups; and the residue of a polyphenol having from six to about eighteeen carbon atoms and from two to about ten phenolic hydroxyl groups;
R3 is selected from the group consisting of hydrogen and P(OR2)2;
Z is the bivalent or trivalent residue of a polyhydric alcohol having from two to about eighteen carbon atoms, and from two to three hydroxyl groups; or of a polyphenol having from six to about eighteen carbon atoms and from two to about ten phenolic hydroxyl groups;
n, is 0 or 1; and
n2 is a number from 1 to 5; as well as synthetic resin compositions having an enhanced resistance to deterioration by heat and/or light due to the presence of an organic phosphite of this class.
