Abstract

The thermal and antimicrobial properties of air drying polyesteramide-urethanes (hybrid) synthesized from Thevetia peruviana (a tropical and underutilized ornamental shrub) seed oil (TPSO) were evaluated. Physico-chemical characterizations (such as hydroxyl value, iodine value, saponification value, refractive index, inherent viscosity) of the resins were carried out using standard procedures. The polyesteramide was synthesized by reacting N, N'- bis(2- hydroxyethyl) Thevetia peruviana (I-IETA) [a product of aminolysis of TPSO] with Isophoronediisocyanate (IPDI). FTIR, 1H-NMR and 13C-NMR spectroscopic methods were used in structural .elucidation of the air dried hybrid urethanes. Antimicrobial activities as well as thermal stability (using TGA and DSC) of the coating films were evaluated. The SEM micrograph of the hybrid film and corrosion inhibitive test was also exa.rilined.
