Synthesis and Applications of Oil-modified Polyesteramide Resins for Surface Coatings

摘要

polyesteramide resins, suitable for coating applications, have been synthesised, using two different oils, viz: a non traditional, nonoxidising type, pilu fat (Salvadora Oleoides) and a traditional oxidizing type, dehydrated castor oil (DCO). N,N- bis-(2-hydroxyethyl) fattyamides (HEFAs) have been prepared by aminolysis of both pilu oil and DCOt with diethanolamine using zinc oxide as a catalyst. HEFAs were reacted with isophthalic acid in varying molar rations to obtain a series of hydroxy terminated polyesteramides (HTPEAs).
