Synthesis of new monomers for preparation of thermal stable poly(ester-imide)s from reaction of melamine and phenyl derivative of melamine and trimelitic anhydride

Polyimides are one of the high-performance polymeric materials, and are characterized by high thermal and thermooxidative stability, good mechanical properties, and outstanding solvent resistance. However, poor thermoplastic fluidity and bad solubility are major problems for wide application of polyimides. One of the typical successful approaches for increase of solubility and processability of polyimides without sacrificing their high thermal stability is synthesis of copolyimides such as poly(ester-imide)s. we report the new poly ester imide monomer which after polymerization possesses both advantages of these two polymers
