Polyetheramide resin based on the condensation polymerisation of N-N-bis (2-hydroxyethyl) Albizia benth oil fatty amide with bisphenol-A was synthesized. The polyetheramide was further modified with urethane linkage resulting from the addition reaction of free hydroxyl groups of the hydroxylethyl Albizia benth oil fatty amide and the isocyanate moeity of toluene 2,4 di-isocyanate. The spectroscopic characterisation (FT-IR, H-1 NMR, C-13 NMR) as well as the thermal, physicochemical and coating properties of the polyetheramide and its urethaned modified derivatives were carried out. Urethanation led to curing at lower temperature, increase in glass transition and improvement in coating properties and resistance to chemical corrosion. (C) 2011 Elsevier B.V. All rights reserved.
