SYNTHESIS, CHARACTERIZATION AND ANTIBACTERIALEVALUATIONS OF NOVEL HYBRID POLYESTERAMIDEURETHANESPREPARED FROM YELLOW OLEANDA SEED OIL
2013
Air drying polyesteramide-urethanes resins were synthesized from Thevetia peruviana
seed oil commonly known as Yellow oleanda (a tropical ornamental shrub) having
about 68.8% unsaturated and 30.9% saturated fatty acids. The physico- chemical
characterization of the optimized unsaturated FAME such as hydroxyl value, iodine
value, saponification value, refractive index, inherent viscosity were carried out using
standard methods. Through condensation reaction the N,N'- bis(2-hydroxyethyl)
Thevetia peruviana (HETA) prepared from the FAME reacted with isophthalic acid to
form polyesteramide. The latter undergo urethanation with H1
'
2MDI. The structural
elucidation of the moisture cured polyesteramide-urethane coating was based on
FTIR, 1H-NMR and 13C-NMR spectroscopic methods. The coatings films were
evaluated for its antihacterial activity and thermal stability properties on TGA and
DSC. The SEM of the --uating films was also examined.
