Alpha-hydroxy-carboxylic acids as curing rate accelerators for curable polymer systems
Abstract
Abstract THIS INVENTION RELATES TO ACCELERATED CURING OF A LIQUID COMPOSITION COMPRISING A POLYENE CONTAINING AT LEAST TWO REACTIVE UNSATURATED CARBON TO CARBON BONDS PER MOLECULE AND A POLYTHIOL CONTAINING AT LEAST TWO THIOL GROUPS PER MOLECULE, THE TOTAL COMBINED FUNCTIONALITY OF (A) THE REACTIVE UNSATURATED CARBON TO CARBON BONDS PER MOLECULE IN THE POLYENE AND (B) THE THIOL GROUPS PER MOLECULE IN THE POLYTHIOL BEING GREATER THAN FOUR, IN THE PRESENCE OF A NOVEL CLASS OF CURING RATE ACCELERATORS FROM THE GROUP CONSISTING OF OXALIC ACID AND N-HYDROXY CARBOXYLIC ACID OF THE FORMULA R-C(-R'')(-OH)-COOH WHEREIN R AND R'' ARE INDEPENDENTLY SELECTED FROM THE GROUP CONSISTING OF -CH2COOH, -CHOHCOOH, HYDROGEN, ARYL, ALKYL CONTAINING 1-18 CARBON ATOMS.
