Abstract
A new class of poly(urethane-imide)s (PUI) thermoplastic elastomers were synthesized via the reaction of NCO terminated polyurethane with imide containing chain extender diols. The prepared chain extenders and polymers were characterized by conventional methods, and physical properties such as solution viscosity, solubility property, thermal stability and thermal behavior were studied. Compared to typical polyurethanes, these polymers exhibited better thermal stabilities due to the presence of the imide groups.
