A METHOD OF CURING A COMPOSITION CONTAINING AS THE SOLE POLYMERIC COMPONENTS, A POLYMERIZED MATERIAL SELECTED FROM THE GROUP CONSISTING OF (1) A POLYMER CONTAINING AT LEAST 2% BY WEIGHT OF UNITS HAVING AN ALCOHOLIC HYDROXYL GROUP ATTACHED TO A CARBON ATOM WHICH IS DIRECTLY ATTACHED SOLELY TO ATOMS SELECTED FROM THE GROUP CONSISTING OF CARBON AND HYDROGEN, SAID POLYMERS CONTAINING AT LEAST 2% BY WEIGHT OF UNITS OF AT LEAST ONE ESTER OF AN A,B-MONOETHYLENEICALLY UNSATURATED ACID, AND (2) A MIXTURE OF (A) A POLYMER CONTAINING UNITS HAVING AN ALCOHOLIC HYDROXYL GROUP ATTACHED TO A CARBON ATOM WHICH IS DIRECTLY ATTACHED SOLELY TO ATOMS SELECTED FROM THE GROUP CONSISTING OF CARBON AND HYDROGEN AND (B) A POLYMER CONTAINING UNITS OF AT LAST ONE ESTER OF AND A,B-MONOETHYLENICALLY UNSATURATED ACID, THE AMOUNT OF THE HYDROXYL-CONTAINING UNITS AND THE AMOUNT OF THE ESTER UNITS EACH BEING AT LEAST 2% BY WEIGHT, BASED ONN THE WEIGHT OF THE MIXTURE OF POLYMERS, WHICH COMPRISES HEATING THE COMPOSITION IN CONTACT WITH 0.1 TO 5% BY WEIGHT, BASED ON THE WEIGHT OF POLYMERIZED MATERIAL THEREIN, OF A COMPOUND SELECTED FROM THE GROUP CONSISTING OF MAGNESIUM PERCHLORATE, ZINC PERCHLORATE, AND MIXTURES THEREOF.
