Process for the preparation of aqueous polymerizate dispersions of unsaturated monomers
Abstract
Abstract THE INVENTION RELATES TO A PROCESS FOR THE PREPARATION OF AQEOUS POLYMERIZATE DISPERSIONS WHICH COMPRISES THE STEPS OF EFFECTING A DISPERSION POLYMERIZATION OF FREERADICAL POLYMERIZABLE ORGANIC COMPOUNDS IN THE PRESENCE OF 0.6% TO 4% BY WEIGHT OF THE POLYMERIZATES OF NVINYLPYRROLIDONE, 0.1% TO 8% BY WEIGHT OF NON-IONIC EMULSIFIERS AND FROM 0% TO 4% BY WEIGHT OF ANIONIC EMULSIFIERS CHARACTERIZED IN THAT ABOUT 0.1% TO ABOUT 0.8% BY WEIGHT OF A WATER-SOLUBLE HYDROXYALKYL CELLULOSE IS ADDITIONALLY PRESENT IN THE POLYMERIZATION RECIPE, WHERE ALL THE ABOVE PERCENTAGES ARE PERCENTAGES BY WEIGHT WITH REFERENCE TO THE WEIGHT OF THE FREE-RADICAL POLYMERIZABLE ORGANIC COMPOUNDS PRESENT IN THE POLYMERIZATION RECIPE.
