A series of polyurethane (MBPUs) with varying stoichiometric balance i.e., isocyanate (NCO): hydroxyl groups (OH) ratio (viz. 1:1, 1.2:1 and 1.4:1), was synthesized using transesterified castor oil and partially biobased isocyanate. The chemical properties, kinetics, thermal stability, morphology and mechanical properties of the MBPUs were analyzed...
