摘要：

Ethylene diamine polyesteramide (Ed-PEA) was synthesized from N, N-bis (2-hydroxy ethyl) linseed oil fattyamide and ethylene diamine tetra acetic acid through condensation polymerization. It was further treated with toluylene 2,4-diisocyanate (TDI) in different weight percentage to obtain urethane-modified polyesteramide (Ed-UPEA). The structural elucidation of Ed-PEA and Ed-UPEA were carried out by FTIR, H-1-NMR, and C-13-NMR spectroscopic techniques. Thermal studies of these resins were carried by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). The coatings of urethane-modified polyesteramide were prepared on mild steel strips and their anticorrosive behavior of in acid, alkali, water, and xylene were investigated. Thermal stability performance suggests that the system could be safely used upto 200 degrees C. (C) 2009 Wiley Periodicals, Inc. J Appl Polym Sci 114: 3268-3273, 2009
