Spectroscopic studies of environmentally sustainable polyurethane composites based on castor oil

Increasing world population demands increasing amount of chemicals, materials, polymers for daily usage. Most of the polymers and chemicals are derived from fossil resources but the major problem of using this fossil based material is undesirable environmental problem, frequent oscillation in oil price and limited fossil resources. In the present study we mainly focus on Synthesis of castor oil based soft polyurethane and its composites. In this study two fibre were selected Sisal and glass were selected. The compound was further subjected to FT-IR and XRD and the swelling coefficient and absorptivity percentage studies.
