Emulsion polymerization process utilizing organosulfur molecular weight modifier premixed with emulsifier and reducing agent

Claim 1

IN A PROCESS OF AQUEOUS EMULSION POLYMERIZATION WHEREIN AT LEAST ONE POLYMERIZABLE MONOMER POLYMERIZED WITH A REDOX OR FREE RADICAL INITIATOR IS POLYMERIZED UNDER AQUEOUS EMULSION POLYMERIZATION CONDITIONS IN THE PRESENCE OF A REDOX OR FREE RADICAL INITIATOR, AQUEOUS EMULSIFIER SOLUTTION, ORGANOSULFUR COMPOUND AS MOLECULAR WEIGHT ;MODIFIER, AND AQUEOUS MEDIUM, THE STEPS COMPRISING: TREATING SAID AQUEOUS EMULSIFFIER SLOUTION BY ADMIXING THEREWITH AT LEAST ONE REDUCING AGENT, ADMIXING SAID COAGITATED ADMIXTURE OF TREATED AQUEOUS EMULSIFIE WITH SAID ORGANSOSULFUR MOLECULAR WEIGHT COMPOUND MODIFIERM COAGITATING THE RESULTING ADMIXTURE SUFFICIENTLY TO INCREASE THE REACTIVITY OF SAID ORGANOSULFURR COMPOUND AS SAID MODIFIER, ADMIXING SAID COAGITATED ADMIXTURE OF TREATED AQUEOUS EMUSLIFIER AND ORGANOSULFUR MOLECULAR WEIGHT MODIFIER WITH SAID POLYMERIZABLE MONOMERR AND INITATOR AND POLYMERIZING THE RESULT POLYMERIZATION ADMIXTURE NDEAQUEOUS EMULSION POLYMERIZATION CONDITIONS, UNDER WHEREIN SAID POLYMERIZABLE MONOMER IS A POLYMERIZABLE CONJUGATED DIENE, POLYMERIZABLE MONOVINYL-SUBSTITUTED AROMATIC COMPOUND OR BOTH , AND CAN FURTHER INCLUDE COPOLYMERIZABLE MONOETHYLENICALLY UNSATURATED MATERIALS AND SAID POLYMERIZATION CAN INCLUDE THE PRESENCENOF AN UNSATURATED ELASTOMER, WHEREIN SAID REDUCILNG AGENT IS HYDROXYLAMINE, HYDRAZINE, A SUBSTITUTED HYDRAZINE, HYDROQUINE, ALDEHYDE, PARALDEHYDE, ALKYL NITRILE , OR A GROUP 1A ALKALI METAL OR AMMONIUM SULFIDE, SULFITE, DITHIONITE, NITRITE, ORTHOSPHOSPHITE, OR A MIXTURE AND WHEREIN SAID REDICING AGENT IS EMP;OYED IN A MINOR AMOUNT EFFECTIVE TO SUBSTANTIALLY PRECENT LOSS OF SAID ORGANOSULFUR COMPOUND MOLECULAR WEIGHTT MODIFIER DURING SAID COAGITATION WHEREIN SAID EMULDIFIER IN SAID AQUEOUS EMULSIFIER SOLUTION IS A NONIONIC OR ANIONIC EMSULSIFIER; AND WHEREIN SAID ORGANOSULFUR COMPOUND MOLECULAR WEIGHT MODIFIER IS A MERCAPTAN, DIALKYLDIXATHOGEN, DIARYLDISULFIDE, TETAALKYLTHIURAM MONOSULFIDE, TETAALKYLTHIURAM DISULFIDE, OR MERCAPTOTHIAZOL.
