Title

Synthesis of Vegetable Oil Derived Polyurethanes

Abstract

Bio-based polyurethanes are desired to replace traditional polyurethanes made from petrochemicals in order to be more environmentally friendly and decrease dependence on nonrenewable fossil energy sources. Vegetable oils are a suitable renewable starting material for bio-based polyurethanes due to their availability and low cost. Vegetable oils are triglycerides composed of different fatty acid chains which depend on the plant and the growing conditions. The chemical and physical properties of the oil depend on the fatty acid composition and degree of unsaturation. In this work, polyols are derived from castor oil through epoxidation of the double bonds followed by ring opening of the epoxide group. The thermal properties of the resulting polyurethanes are studied using differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA).
