Article Description

Seed oil based polyurethane resins were synthesized from underutilized plant seedlings of Thevetia peruviana (yellow oleanda). The seed oil was converted to partial glycerides (PG) polyol using calcium oxide as catalyst. The polyol was treated with varying ratios of isophorone diisocyanate (IPDI) in order to synthesize partial glyceride urethanes (PGU) films. The PG intermediate and PGU products were characterized using FT-IR, H-NMR andC-NMR. Physico-chemical parameters like acid value, hydroxyl value, viscosity and refractive index were also examined. Corrosion stability of coated panels was studied in the salt spray chamber. Thermal stability and antimicrobial study of the films were also evaluated.
