Thermal behavior of halogenated imide-bismaleimide resins

الملخص EN

Several new poly-halogenated maleimides.

bismaleimides and their copoly resins were synthesised thermally from their corresponding amic acids.

The synthesis was accomplished by two way method (amic acid - poly imide) instead of the well-known three way method (amic acid - imide - polvimide).

Thermal characterization of monomers and their cured resins was achieved using differential thermal analysis (DTA), dynamic thermogravimetric analysis (TGA) and isothermal gravimetric analysis (IGA).

The effect of halogen substituent, especially in the ortho position, is clear in the imidization process.

while polymerization proceeds almost equally in all systems.

Thermal properties of homo and copolymers were correlated with their chemical structures.
