| abstract |
The antioxidant polymer of the present invention comprises a repeating unit comprising one or both of structural formulas (I) and (II), wherein R is -H, or a substituted or unsubstituted alkyl group, acyl group, or aryl. Ring A is substituted by at least one tert-butyl group or substituted or unsubstituted n-alkoxycarbonyl group; ring B is at least one -H, and at least one tert-butyl group or substituted or Substituted by an unsubstituted n-alkoxycarbonyl group; rings A and B are each selected from the group consisting of —OH, —NH, —SH, a substituted or unsubstituted alkyl group or aryl group, and a substituted or unsubstituted alkoxycarbonyl group; Optionally substituted with one or more selected groups; n is an integer greater than or equal to 2; and p is an integer greater than or equal to 0. The invention also includes methods for using and preparing these polymers. |
