Hindered bis-phenol phenyl phosphites are provided having the structure:
wherein:
R 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; alkaryl and aryl having from six to about eighteen carbon atoms; preferably, a bulky group such as iso, secondary or tertiary alkyl having from three to about ten carbon atoms; or cycloalkyl having six to twelve carbon atoms;
R, and R2 are each selected from the group consisting of hydrogen; alkyl having from one to about eighteen carbon atoms; cycloalkyl having from three up to about twelve carbon atoms; alkaryl and aryl having from six to about eighteen carbon atoms; and are preferably in a position ortho to a phenolic hydroxyl or phenoxy group, if available;
R3 is alkylene having from one to about six carbon atoms;
R4 is selected from the group consisting of alkylene, cycloalkylene, and aralkylene, the residue of a monohydric or polyhydric alcohol, having from one to about eighteen carbon atoms, and from none to three hydroxyl groups (originally one to four hydroxyl groups);
Y is selected from the group consisting of a direct carbon to carbon bond; thio sulfur -S-; oxy oxygen -0-; alkylidene having from one to about six carbon atoms; and cycloalkylidene having from four to about eight carbon atoms; and
n is 1, 2, 3, or 4, according to the valence of R4; 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.
