Synthesis of some polyesteramide resins modified by nicotinic and isonicotinic acid derivativs

Various polyesteramide resins are prepared in which a stoichiometric amount of hydroxy ethyl fatty acid amides (diol) are replaced by the bifunctional nicotinic acid and aisonicotinic acid derivatives of diethanolamine and triethanolamine without affecting the resin constants. The inclusion of nicotinyl and isonicotinyl residues would expect to prevent microbial growth and may also act as corrosion inhibitor.
