Abstract

Alkyd resins based on Jatropha curcas oil with different molar ratios of phthalic anhydride (PA) and maleic anhydride (MA) were prepared by alcoholysis followed by polyesterifi cation reaction. The progress of the reaction was traced by the determination of acid value at regular time intervals. From the kinetic study the extent of the reaction was found in the range of 52.4–61.2%. The prepared resins were blended with a commercially available fast-curing epoxy resin in order to improve the properties like curing time, chemical resistance, tensile strength, and thermal stability. The morphology study of the blends showed good compatibility of alkyd and epoxy resins. On blending with epoxy the tensile strength of the alkyd resins improved signifi cantly and the thermal stability increased by 20ºC. From the various properties of the blends it was observed that the blend with 100% phthalic anhydride has the best performance characteristics and is the most effi cient. The blends possess properties that are much more superior in many aspects than the individual components and have potential for application as coatings.
