Alkylidene bisphenol phosphites and phosphates having 2,2,6,6-tetramethyl piperidinyl groups and synthetic resin composition

Abstract

Alkylidene bisphenol phosphites and phosphates having 2,2,6,6-tetramethyl piperidinyl groups are provided having the formula: ##STR1## wherein: R.sub.1 is alkyl having from one to about twelve carbon atoms; R.sub.2, R.sub.3 and R.sub.4 are each selected from the group consisting of hydrogen and alkyl having from one to about twelve carbon atoms; m is 0 or 1; n is 0 or 1; X is selected from the group consisting of ##STR2## wherein: R.sub.5 is selected from the group consisting of hydrogen, oxyl O.sup.2, alkyl having from one to about twelve carbon atoms; arylalkyl having from seven to about eighteen carbon atoms; 2,3-epoxypropyl, acyl having from one to about eight carbon atoms and ##STR3## in which R.sub.6 is selected from the group consisting of hydrogen, alkyl having from one to about twelve carbon atoms and phenyl, and Y.sub.1 is selected from the group consisting of hydrogen; acyl having from one to about twelve carbon atoms; and ##STR4## Z.sub.1 is selected from the group consisting of ##STR5## wherein R.sub.7 is alkyl from one to about twelve carbon atoms; and ##STR6## wherein: R.sub.6 is selected from the group consisting of hydrogen, alkyl having from one to about twelve carbon atoms and phenyl; and Z.sub.2 is selected from the group consisting of ##STR7## in which R.sub.7 is alkyl having from one to about twelve carbon atoms; R.sub.6 is alkylene having from one to about eight carbon atoms and Y.sub.2 is selected from the group consisting of hydrogen and acyl having from one to about eight carbon atoms.
