Abstract
A simple procedure is proposed for determining the concentration of maleimide and acrylate groups in organic compounds based on the addition of morpholine to the activated double bond by the Michael reaction, followed by the potentiometric titration of the reaction mixture with 1 M HCl in ethanol. The applicability of the method to N-substituted maleimides with aromatic, aliphatic, and oligomeric substituents, as well as to acrylates and acrylonitrile, is verified. It is demonstrated that maleimides and acrylates can be determined simultaneously.
