Abstract
A low-molecular-weight poly(lactic acid) was synthesized through the condensation reaction of L-lactic acid. The effects that the catalyst and temperature have on the reaction rate were studied to determine the optimum reaction conditions. The reaction kinetics increased with temperature up to 210°C, but no further increase was observed above this temperature. Among a few selective catalysts, sulfuric acid was the most effective because it maximized the polymerization reaction rate. Reduction of the pressure was another important factor that enhanced this reactions kinetics.
