Abstract
Cast polyurethanes based on castor oil, fluorescein and tolylene diiso cyanate have been synthesized. The polyurethanes were characterized by Fourier transform infrared spectroscopy. The thermal stabilities of t he polymers were determined using a thermogravimetric analyser. From t he differential scanning calorimetric analysis, change in the glass tr ansition temperature of the soft segment was observed as the molar rat io and feed composition of the fluorescein were varied.
