摘要：
Hindered bisphenol diphosphonites are provided having the structure:
wherein:
A is selected from the group consisting of -S-; -0-; alkylidene having from one to about ten carbon atoms; cycloalkylidene having from about four to about eight carbon atoms; and phenylalkylidene having from seven to about twelve carbon atoms;
R is selected from the group consisting of alkyl having from one to about eighteen carbon atoms; cycloalkyl having from three to about twelve carbon atoms; and aralkyl having from seven to about twelve carbon atoms;
R, is selected from the group consisting of hydrogen; alkyl having from one to about eighteen carbon atoms; cycloalkyl having from three to about twelve carbon atoms; and aralkyl having from seven to about twelve carbon atoms;
R 2 is selected from the group consisting of
and
as well as synthetic resin compositions having an enhanced resistance to deterioration by heat and light comprising a synthetic resin and such phosphonites.
