    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.

    摘要: Disclosed are compositions comprising antioxidants and stabilizers, such as, acid scavengers or organic phosphorus stabilizers, and optionally further comprising co-stabilizers. The disclosed compositions are useful as stabilizers for polyolefins and other polymeric materials. The disclosed compositions and methods generally provide longer shelf lifes and better oxidative resistance to materials than currently available antioxidants.
