Influence of Polybasic Acid Type on Physicochemical Properties of Pine Seed Oil Alkyd Resin

Pine seed oil was employed in the preparation of different medium length alkyd resin samples using alcoholysis and poly condensation process. The alkyds formation was monitored by determining the acid number of the reaction mixture at time intervals and the extents of the polyesterification reactions were evaluated. Both the Pine seed oil and its alkyd resins were characterized by Fourier Transform Infra red (FTIR) spectroscopy. Performance evaluation shows that properties of alkyd resin derived from Maliec anhydride are comparable with phthalic anhydride alkyd resins. However the Maliec alkyd resin shows better color, and lower poly condensation time. Better results were observed from the blending of phthalic and small portions of maliec anhydride.
