Abstract: The method of nonaqueous potentiometric titration enables to determine the content of itaconic acid or its monoesters in copolymers which are insoluble in water. This simple and suitable method requires a small amount of the sample. The determination of inflection point on the titration curve is performed numerically. The method was used for the composition determination of the following copolymers: styrene with itaconic acid, methyl methacrylate with itaconic acid, and methyl methacrylate with 4-methyl itaconate.
