Moisture‐cured polyurethane films have been prepared by reaction between toluene diisocyanate and castor oil or derivatives such as castor oil diethanol amide, castor oil monoglyceride, ethylene glycol monoricinoleate, and propylene glycol monoricinoleate. Effect of acetylated castor oil as an internal plasticizer on the resulting urethane films has been studied. Catalytic effect of 3–5% triethanol amine on curing of plasticized films has been noted. Plasticized polyurethane films show good tensile strength (105–550 kg/cm 2 ) and elongation (15–215%) properties, having high melting point (210–272 C) and good resistance to solvents and chemicals.
