Claim 1
Independent Claim
111 words
A PROCESS FOR MAKING A SPRAY-DRIED SOLID, PARTICULATE WATER-DISPERSIBLE POLYSULFIDE POLYMER COMPOSITION WHICH COMPRISES FORMING A LATEX WHICH IS AN AQUEOUS DISPERSION OF THE REACTION PRODUCT OF AN ORGANIC POLYTHIOSULFATE WHEREIN THE ORGANIC RADICAL IS SELECTED FROM THE GROUP CONSISTING OF OXAHYDROCARBON AND ALIPHATIC HYDROCARBON RADICALS HAVING UP TO 10 CARBON ATOMS AND A REAGENT SELECTED FROM THE GROUP CONSISTING OF ALKALI METAL AND ALKALINE EARTH METAL MONOSULFIDES, POLYSULFIDES, AND SULFAHYDRATES, SAID LATEX INCLUDING FROM 0.1% TO 40% OF A DISPERSING AGENT BASED ON THE WEIGHT OF SAID REACTION PRODUCT, ATOMIZING THE FRESHLY PREPARED LATEX AND SPRAYING THE ATOMIZED LATEX INTO A BODY OF HEATED AIR TO FORM WATER-DISPERSIBLE POLYMER PARTICLES.
