Polyenes cured with polythiols with iron compounds and oxime ester as accelerators
Abstract
Abstract THIS INVENTION RELATES TO ACCELERATED CURING UNDER AMBIENT CONDITIONS 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 PREENCE OF A CURING RATE ACCELERATOR COMPRISING A CATALYTIC AMOUNT OF IRON AND ITS COMPOUNDS. THE ADDITION OF A MINOR AMOUNT OF AN OXIME ESTER TO THE SYSTEM ALLOWS ONE TO CURE IN AN INERT ATMOSPHERE. THE POLYTHIOETHERS FORMED CAN BE USED AS ADHESIVES.
