WebTermination: Eventually, two radicals meet each other and combine to form a non-radical product. This could be two acrylate radicals or an acrylate radical plus another initiator radical. Or, if water/oxygen are present, it could react with those to form a complicated mix of things, none of which are reactive anymore.
