Abstract: THIS INVENTION RELATES TO NEW SULPHENAMIDES OF 2FORMYL PROPYL-2-SULPHENIC ACID AND THEIR USE IN THE PRODUCTION AND PROCESSING OF MIXTURES BASED ON A NATURAL OR SYNTHETIC RUBBER. THE NOVEL COMPOUNDS ARE PREPARED BY REACTING 2-FORMYL PROPYL-2-SULPHENIC CHLORIDE WITH AMINES AND AMIDES IN THE PRESENCE OF AN ACID BINDING AGENT. THE RETARDERS CAN BE MIXED INTO THE RUBBER IN THE USUAL WAY.
