摘要

Poly(urethane-fatty amide) (PUPGFA) was developed to use nonedible and nondrying Pongamia glabra seed oil. The resin was synthesized by the reaction of N,N-bis(2-hydroxyethyl) P. glabra fatty amide (HEPGFA) and tolylene-2,4- diisocyanate through a one-shot technique with a minimal amount (8-10%) of organic solvent. The structural elucidation of the resin was carried out by Fourier transform infrared (FTIR), ~1H-NMR, and ~(13)C-NMR spectroscopic techniques, whereas the curing mechanism was confirmed by FTIR spectroscopy and differential scanning calorimetry. The solubility of the resin was studied in different polar and nonpolar solvents. Thermal analysis was carried out by thermogravimetric analysis and differential thermal analysis techniques. Antibacterial studies of HEPGFA and PUPGFA were performed in the presence of Gram-negative Salmonella and Gram-positive Staphylococcus aureus bacteria by an agar diffusion method. Physicochemical, physicomechanical, and corrosion-resistance tests were performed by standard laboratory methods. PUPGFA had good physicomechanical properties, excellent chemical/corrosion resistance, and moderate antibacterial activities.
