Abstract
Abstract NEW COMPOUNDS WITH A NUCLEUS OF R-S-S-N(-)-CO- WHERE THE DANGLING VALENCE ON THE NITROGEN IS LINKED TO A SECOND CARBONYL, ALKYL, ARYL, CYCLOALKYL, HYDROGEN, ALKYLENE CARBON, OR ARYLENE CARBON AND R IS ALKYL, ARYL, OR CYCLOALKYL ARE INHIBITORS OF PREMATURE VULCANIZATION OF DIENE RUBBERS. COMPOUNDS OF THE FORMULA R"''-S-S-N(-X'')-X WHERE X IS CYCLOALKYL, ALKYL, ARYL, OR HYDROGEN AND X'' IS CYCLOALKYL, ALKYL, OR ARYL; OR X AND X'' TOGETHER WITH THE N ATOM FORM A HETEROCYCLIC AMINE; AND R"'' IS ARYL, ALKYL, OR CYCLOALKYL ARE ALSO INHIBITORS OF PREMATURE VULCANIZATION OF DIENE RUBBERS. A COMBINATION OF A VULCANIZATION ACCELERATOR AND AN INHIBITOR OF THIS INVENTION IS AN IMPROVED RUBBER ADDITIVE WHICH ALLOWS LONGER AND SAFER PROCESSING TIME FOR RUBBER.
