摘要： One group of polymers comprise repeat units of Structural Formula (I) and/or (II) where: R is -H or a substituted or unsubstituted alkyl, acyl or aryl group; Rings A and B are substituted with at least one tert-butyl group, 1-ethenyl-2-carboxylic acid group or ester thereof, substituted or unsubstituted alkylenedioxy group, or substituted or unsubstituted n-alkoxycarbonyl group and optionally additional functional groups; Ring B is additionally substituted with at least one -H; n is equal to or greater than 2; and p is equal to or greater than 0. The polymer typically includes at least two substituted benzene repeat units that are directly connected by C-C or C-O-C bonds between benzene rings. Alternatively, each repeat unit of the polymer is an antioxidant. The invention also includes methods of making and using these and related polymers, particularly as antioxidants.

摘要： 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; and p is an integer equal to or greater than 0. The invention also includes methods of using and preparing these polymers.
