Abstract
A series of bismaleimide monomers and polyaspartimides with various structures were synthesized and their structures were confirmed by Fourier transform infrared (FTIR) and proton nuclear resonance (1H-NMR) spectroscopy. Chain extension of bismaleimides was accomplished by incorporating various ether or other groups. Polymers based on these bismaleimides were prepared by the Michael addition of diamines with various structures to bismaleimides. Thermal and dielectric properties of these polymers were studied.
