Abstract

Poly(urethane-imide)s were prepared by polycondensation reaction of four imides containing DIISOCYANATEs with poly (tetramethylene oxide) glycol. Synthetic procedures for the preparation of the DIISOCYANATEs were described. The chemical structures of the monomers and polymers obtained were characterized by IR, 1H NMR, and mass spectroscopies. The physical properties of polymers including solution viscosity, solubility properties, THERMAL STABILITY and thermal behaviour were studied as well. The polymers showed excellent solubility in polar aprotic solvents such as DMF, DMAc and NMP. Their inherent viscosities were in the range of 0.50-0.55 dL/g. T10 % obtained as a criterion of THERMAL STABILITY was in the range of 316-335 degreesC for the polymers.
