Development of Poly ( Ester Amide - Urethanes ) from De - saturated Thevetia peruviana Seed Oil - FAMEs

This study present the synthesis of eco - friendly poly(ester amide - urethane) coating from Thevetia peruviana seed oil (TPSO). FT - IR, 1 H NMR and 13 C NMR spectral analyses were used in confirming the structure of compounds. Physico - chemical properties of desaturated N,N' - bis (2 hydroxyethyl) Thevetia peruviana seed oil fatty amide (DHETA), poly(ester amide) (PESA) and poly(ester amide urethanes) (PESA U), as well as chemical resistance, antibacterial studies and thermal analysis of PESAU were also examined. Aims: To evaluate the thermal stability and antibacterial activities of PESAU. Study Design: Extraction of seed oil from the air - dried seedlings of Thevetia peruviana seeds and preparation of polyol through urea fractionation. Followed by urethane synthesis using 4,4'
