Abstract
This study describes the preparation and characterization of new starch cross-linked polyurethanes produced by the reaction of native cornstarch with a propylene oxide toluene diisocyanate oligomer. Infrared analysis confirmed the occurrence of the reaction and solubility and swelling tests showed that it had led to cross-linked structures. These products were totally amorphous and displayed elastomeric properties associated with two Tgs at −60 and 35 °C.
