    Abstract: Two different alkyd resins; epoxidized neem seed oil-modified alkyd resin (ENOMAR) and crude neem seed oil-modified alkyd resin (CNOMAR) with oil-length of 64.5% each were synthesized. A portion of neem oil was epoxidized at 50°C using per-acid generated in-situ. The (ENOMAR) and (CNOMAR) were prepared using glycolysis and poly-condensation methods... Show More
