Abstract

This paper describes the synthesis and characterization of six structurally different bismaleimides. They were prepared by reacting maleic anhydride with diamines containing ether and thioether bridges. Thermal polymerization of these monomers in the presence or absence of radical initiators was investigated by differential scanning calorimetry. Activation energy (E), kinetic order (n), rate constants (k) and heat of polymerization (Δ__H__) were determined. The cured resins are stable up to 334–418°C both in argon and air atmosphere.
