ABSTRACT:
Antioxidant polymers of the present invention comprise repeat units that include one or both of Structural Formulas (I) and (II):wherein:R is —H or a substituted or unsubstituted alkyl, acyl or aryl group;Ring A is substituted with at least one tert-butyl group or substituted or unsubstituted n-alkoxycarbonyl group;Ring B is substituted with at least one —H and at least one tert-butyl group or substituted or unsubstituted n-alkoxycarbonyl group;Rings A and B are each optionally substituted with one or more groups selected from the group consisting of —OH, —NH, —SH, a substituted or unsubstituted alkyl or aryl group, and a substituted or unsubstituted alkoxycarbonyl group;n is an integer equal to or greater than 2; andp is an integer equal to or greater than 0.The invention also includes methods of using and preparing these polymers.
