Abstract: The present invention is directed to compositions which may undergo thermolysis to produce a higher purity acrylic acid product. In preferred embodiments of the present invention, the compositions comprise polypropiolactone and one or more active salts. The one or more active salts may catalyze thermolysis of the polypropiolactone so that the polymer depolymerizes into acrylic acid monomers. Certain concentrations of the one or more active salts result in higher purity acrylic acid products of thermolysis. In certain preferred embodiments, the one or more active salts include an acrylate group which may decompose under thermolysis to provide acrylic acid and thus decrease the concentration of undesirable contaminants in the acrylic acid product. In certain preferred embodiment, the one or more active salts comprise sodium acrylate.
