    Abstract: Provided are novel 4- and 5-substituted 1,2,3-triazoles, and regioisomer mixtures thereof, modified polymers, wherein the substituted 1,2,3-triazoles are modified by reaction with a modifying polymer (maleic anhydride based polymer). Depending upon the ratio of the substituted 1,2,3-triazole to the maleic anhydride based polymer employed, the resulting modified polymers can provide maleic anhydride based polymers that are partially or fully reacted with the substituted 1,2,3-triazoles. The resulting modified polymers may be partially or fully opened to provide amic acids, carboxylic acids, carboxylic acidic salts, imides, or esters. The novel 4- or 5-substituted 1,2,3-triazoles, and regioisomer mixtures thereof, modified polymers can be converted to a wide variety of useful polymers and may be employed in a wide variety of compositions. An example of a modified polymer may be represented by the structure: formula: (1) wherein m, n, and q are defined herein.
