THE METHOD OF TERMINATING THE POLYMERIZATION OF A MONOMERIC MATERIAL IN AQUEOUS EMULSION COMPRISING A BUTADIENE-1,3 HYDROCARBON WHICH COMPRISES ADDING TO SAID EMULSION AFTER THE BEGINNING OF THE POLYMERIZATION AND PRIOR TO COMPLETION THEREOF, A COMBINATION OF SUBSTANCES CONSISTING OF (1) A SOLUTION OF AN AGENT SELECTED FROM THE CLASS CONSISTINGOF SULFUR, ALKYL THIURAM POLYSULFIDES, ALKYL XANTHOGEN POLYSULFIDES AND WATER-SOLUBLE INORGANIC POLYSULFIDES AND (2) AN AQUEOUS SOLUTION OF A WATER-SOLUBLE SALT OF A DITHIOCARBAMIC ACID, SUBSTANCE (1) BEING ADDED IN AMOUNTS EQUIVALENT TO FROM 0.01 TO 0.10% BY WEIGHT OF SULFUR AND SUBSTANCE (2) BEING ADDED IN AMOUNTS OF FROM 0.01 TO 0.10% BY WEIGHT, BASED ON THE WEIGHT OF MONOMER INITIALLY PRESENT IN SAID EMULSION.
