ABSTRACT = {Thermosetting polyurethanes are widely used in various fields owing to
their excellent elasticity, strength and solvent resistance. Three environmental
friendly propyl gallate-based self-healing polyurethanes were prepared from polyurethane prepolymers with varying isocyanate content. The thermal stabilities of the
polyurethanes were tested using thermogravimetric analysis. Their self-healing and
mechanical properties were analyzed using a universal testing machine and dynamic
thermomechanical analysis. The polyurethanes were found with high self-healing
ability and excellent mechanical properties due to the absence of phenolic carbamate.
These qualities improved with increased isocyanate content and the prolonged selfhealing time. We found, therefore, that the propyl gallate-based polyurethane has
potential for use in industrial applications as self-healing materials.},
