Abstract
New polyesters with maleimide pendent groups have been synthesized by direct solution polycondensation reaction between 4-42 - dihydroxy- biphenyl and two functional bismaleimides containing carboxylic functionalities. The products were characterized by infrared and proton nuclear magnetic resonance spectroscopy. Thermal properties of the new synthesized copolymers were studied by thermogravimetric analyses and differential scanning calorimetry. Keywords: bismaleimides, polyesters, thermal stability
