Phthalic anhydride-glycerol Resin(PAGR) increase the flexibility of paint, resist to acid rain effect, increases the adhesiveness, brushing power, film hardness, layer flexibility, durability, gloss retention, resistance to abrasion also helps to decrease the overall drying time of paints. Phthalic anhydride-glycerol Resin is produced by reacting polyfunctional alcohol with the poly basic and monofunctional acid by Alcoholysis process. Moreover, Phthalic anhydride-glycerol Resin (PAGR) is a major raw material for coatings, varnishes and binders. Phthalic anhydride-glycerol Resin (PAGR) is used in paints coating compositions, adhesive, plastics, varnishes, printing ink, floor coverings. In the present research work, Phthalic anhydride-glycerol Resin is synthesized using soybean oil, pentaerythritol, phthalic anhydride and litharge (PbO). It was further characterized by FTIR, DSC TGA and acid value.
