Abstract

The kinetics of polyesterification of glycerol, phthalic anhydride and jatropha oil leading to the formation of alkyd resins were studied. A series of alkyd resins having different amount of jatropha oil viz., 40-80% have been prepared by employing two stage alcoholysis-polyesterification process. The extent of reaction and average degree of polymerisation were calculated from the end group analysis of the reaction mixture withdrawn at regular intervals of time. The initial reaction rates followed the second order kinetics and thereafter deviations were observed. An appreciable degree of conversion was noticed from the extent of the reaction which lies in the range of 49. 5-62. 5%. The average degree of polymerisation calculated in the region of deviation from second order suggested the occurrence of chain branching at relatively shorter intervals along the polymer chain. The second order rate constants were found to be of the order of 10 -5 g (mg KOH) -1 min -1.
