Thermal Behavior of New Polymaleamides

摘要

Novel polymaleamides have been prepared from bisfurilic nialamide monomers and bismaleimides by the Diels-Alder reactions. The bisfurilic monomers were synthesized by the ring opening reaction of bisisomaleimides with 2-furfuryIamine. The structure of monomers and polymers was confirmed by the FT-IR and 'H-NMR spectroscopies and elemental analysis. The polymers based on the bismaleimide having a rigid structure gave brittle films and the polymers containing urethane groups resulted in elastic films. The thermal behavior of polymers was investigated by the thermogravimetric, dynamic mechanical and DSC measurements and dielectrical spectroscopy.
