THE METHOD FOR PREPARING AN EMULSION OF A POLYVINYL ACETATE RESIN COMPOSED OF A FAMILY OF SPHERICAL, UNIFORM SIZE PARTICLES HAVING A DIAMETER WITHIN THE RANGE OF 0.1 TO 10 MICRONS, COMPRISING POLYMERIZING A MIXTURE OF FROM 60 TO 100% BY WEIGHT OF VINYL ACETATE AND FROM 0 TO 40% BY WEIGHT OF AT LEAST ONE OTHER MONOMER COPOLYMERIZABLE WITH VINYL ACETATE SELECTED FROM THE GROUP CONSISTING OF ALKYL ESTERS OF AN ALPHA, BETA OLEFINICALLY UNSATURATED CARBOXYLIC ACID WHEREIN THE CARBOXYLIC ACID HAS FROM 3 TO 6 CARBON ATOMS AND THE ALKYL ESTER GROUP CONTAINS FROM 1 TO 12 CARBON ATOMS, IN THE PRESENCE OF FROM 0.01 PART TO 3.0 PARTS BY WEIGHT PER 100 PARTS OF THE MONOMERS OF A FRE-RADIAL CATALYST AND FROM 0.01 TO 5.0 PARTS BY WEIGHT PER 100 PARTS OF THE MONOMERS OF AN INSOLUBLE SOAP AS THE SOLE EMULSIFIER SAID SOAP HAVING A STRUCTURE (X-COO)NM WHEREIN X REPRESENTS AN ALKYL GROUP HAVING FROM 7 TO 21 CARBON ATOMS AND M IS A MEMBER SELECTED FROM THE GROUP CONSISTING OF LITHIUM, BARIUM, CALCIUM, MAGNESIUM, CADMIUM, ZINC, LEAD, TIN AND ALUMINUM AND N IS A WHOLE NUMBER EQUAL TO THE VALENCE OF M, WITH AGITATION IN THE SUBSTANTIAL ABSENCE OF OXYGEN AT A TEMPERATURE BELOW ABOUT 100*C.
