Abstract
A combination of free radical retarding agent and an active iodine species selected from the group consisting of molecular iodine, iodide ion, and mixtures thereof provides synergistic stabilization of thiol-ene compositions which cure by addition of thiol groups to olefinic carbon-carbon double bonds. The combination is particularly suitable for thiol-ene formulations employing norbornenyl functional polyenes. A preferred stabilization system employs an N-nitrosoarylhydroxylamine salt and a mixture of an alkali iodide and I.sub.2 in the range of 0.6-1 mole I.sub.2 per equivalent I.sup..crclbar..
