A simple and practical solvent-free preparation of polymaleimide

Molecules. 2011 Feb 28;16(3):1981-6. doi: 10.3390/molecules16031981.

Abstract

Polymaleimide (PMAI) was synthesized by reacting polymaleic anhydride (PMA) with urea via a solvent-free reaction at 180 °C. The conversion of PMA could reach 95%. This method is simple, practical and environmentally-friendly. The structure of the resulting PMAI was characterized by ¹H-NMR and IR.
