Abstract

Castor seed oil (Ricinuscommunis) is a vital renewable base material for industrial production of lubricants, brake fluids, soaps, inks, pharmaceuticals, pla stics, perfumes etc. The presence of reachricinoleic acid (about 87.5%) content in its fatty acids profile confers on its essential use for coating purposes. This paper presents the synthesis, characterization and antibacterial evaluations of polyetheramide-urethanes (PETAU) prepared from Ricinuscommunis seed oil. N,N'-bis (2- hydroxyethyl) Ricinuscommunis fatty amide (HERA) was synthesized via aminolysis. Upon reacting HERA with bisphenoiA, polyetheramide (PETA) resin was form ed. The polyetheramide subsequently undergo urethanation to form PETAU. The synthesized PETAU was characterized by FT-IR, 'H-NMR and 13C-NMR spectroscopic analyses. Selected physico-chemical parameters of seed oil, HERA, PETA, PET AU were measured. Coating performance, thermal stability and antimicrobia l properties ofthe cured resin were also evaluated.
