Abstract

Reactions between dicarboxylic acids and diols in the melt and leading to an equilibrium yield quantitative results which may be applied to the kinetics of some partial reactions of polyesterification. The relationship of the rate constants of the forward and the reverse reaction as well as of the equilibrium constant furnish valid results both in the absence of catalyst and in the presence of acid or basic catalysts. The values obtained for the energy of activation of the forward and the reverse reaction and of the overall reaction (13 ± 1 kcal/mole) also are in good agreement.
