Preparation and polymerization of bismaleimide compounds



Bismaleimides with main chains of different structures were prepared by the reaction between maleic anhydride and various diamines and by the reaction between 4-maleimidobenzoylchloride and 3,5-dihidroxybenzoic acid. The monomers were characterized with IR and 1H-NMR spectroscopy. Polymers based on these compounds were prepared through the Michael addition of diamines to bismaleimides. The thermal characterization of the monomers and polymers was performed with differential scanning calorimetry and dynamic thermogravimetric analysis. © 2007 Wiley Periodicals, Inc.
