ABSTRACT:
Novel 1-hydrocarbyl-3-(thiocarbamoylthio)ureas and 1-hydrocarbyl-3-(carbamoylthio)ureas are prepared by reacting, in liquid phase, an appropriate isocyanate and S-thiocarbamoylhydrosulfamine or S-carbamoylhydrosulfamine, e.g., S-(dimethylthiocarbamoyl)-N-methylhydrosulfamine or S-(dimethylcarbamoyl)hydrosulfamine. All the compounds are useful as rubber-curing agents.
