AbstractLinseed oil was employed to modify polyesteramide resin via the condensation of hydroxyethylamide derivatives of fatty acids of linseed oil, i.e. {N, N 0 -bis(2 hydroxylethyl) linseed amide} and phthalic anhydride and dicarboxylic acids such as adipic acid, succinic acid and sebacic acid. The polyesteramide resins obtained were tested for their application as a vehicle/binder in the preparation of surface coatings. The resins obtained were also characterised for their physico-chemical properties, film forming properties and chemical resistance.

Attempt has been made in this study, to utilize castor oil in the preparation of polyesteramide resins. Castor oil was first converted into dehydrated castor oils (DCO) to improve drying characteristics. DCO was then converted into diethanolamide {(N, N‐ bis hydroxethyl) castor oil amide} of mixed fatty acids using 0.5 per cent sodium methoxide as a catalyst and converted to polyesteramide resins after reacting with various dibasic acids such as phthalic anhydride, sebacic, succinic and adipic acids in presence of xylene as azeotropic solvent. The resins obtained were then analysed for its physico‐chemical, film performance properties and resistance to various chemicals.

Polyesteramide resin based on the condensation of hydroxyethylamide derivatives of fatty acids of soybean {N, N′‐bis(2 hydroxyethyl)soybean amide} and various dibasic acid and anhydride were synthesized. Physico‐chemical characteristics and film forming properties of these resins were determined to prove its suitability as a vehicle for surface coatings. The study reveals that resins can be used for the baked type of finishes.
