Method of increasing particle size in synthetic rubber latex by treatment with volatile salt and polyethylene polyamine

Claim 1

THE METHOD OF INCREASING THE SIZE OF THE DISPERSED POLYMER PARTICLES IN A SYNTHETIC RUBBER LATEX AQUEOUS EMULSION POLYMRIZATE OF MATERIAL SELECTED FROM THE GROUP CONSISTING OF BUTADIENES-1,3 AND MIXTURES OF BUTADIENES1,3 WITH UP TO 70% BY WEIGHT OF SUCH MIXTURES OF MONOETHYLENIC COMPOUNDS WHICH CONTAIN A CH2=C< GROUP AND ARE COPOLYMERIZABLE WITH BUTADIENES-1,3 WHICH COMPRISES ADDING TO THE LATEX 2% TO 15% OF A VOLATILE ELECTROLYTE SELECTED FROM THE GROUP CONSISTING OF AMMONIUM AND AMINE SALTS THAT CAN BE VALATILIZED FROM AQUEOUS SOLUTION AT TEMPERATURES UP TO 100*C. AND 0.03% TO 1% OF POLYETHYLENE POLYAMINE SELECTED FROM THE GROUP CONSISTING OF DIETHYLENE TRIAMINE, TRIETHYLENE TETRAMINE, TETRAETHYLENE PENTAMINE, PENTAETHYLENE HEXAMINE, HEXAETHYLENE HEPTAMINE, HEPTAETHYLENE OCTAMINE AND HIGHER POLYETHYLENE POLYAMINES FROM THE STILL BOTTOM FORM THE DISTILLATION RECOVERY OF THE LOWER POLYETHYLENE POLYAMINES FROM THE PRODUCT OF THE REACTION OF ETHYLENE DICHLORIDE AND AMMONIA, SAID PERCENTAGES BEING BASED ON THE WEIGHT OF THE SOLIDS OF THE LATEX.
