【Abstract】 The catalytic behaviour of some solid acids on the polyesterification reaction wasinvestigated. The effect of surface acidity, conditions of catalyst preparation and mole-cule structure of reactants on the polyesterification of alkyd resins was discussed. It wasfound that in conditions near to that for Industrial preparation the kinetics of the hetero-geneous catalytic polyesterification of alkyd resins appeared the same as in the case ofhomogeneous reaction.更多还原
