Interpolymerization of acrylamide,vinyl acetate and other monomers by using a solubilizing agent to dissolve the acrylamide in the vinyl acetate
Abstract
Abstract PROCESS FOR AQUEOUS EMULSION INTERPOLYMERIZATION OF VINYL ACETATE AND ACRYLAMIDE WITH OR WITHOUT ADDITIONAL MONOMERS IN PROPORTIONS TO FORM STABLE 50-70% INTERPOLYMER SOLIDS EMULSIONS, WITH 2-15% ACRYLAMIDE BY WEIGHT OF THE OTHER MONOMERS IN THE INTERPOLYMER, BY DISSOLVING THE ACRYLAMIDE IN THE VINYL ACETATE WITH THE AID OF A SOLUBILIZING AGENT BEFORE DISPERSING THE MONOMERS IN AN AQUEOUS MEDIUM FOR INTERPOLYMERIZATION. EXAMPLES OF SUITABLE SPECIFIC SOLUBLIZING AGENTS ARE METHANOL AND FORMAMIDE, MATERIALS WHICH RENDER ACRYLAMIDE SOLUBLE IN VINYL ACETATE AND DO NOT INTERFERE WITH SUBSEQUENT INTERPOLYMERIZATION NOR ADVERSELY AFFECT THE PROPERTIES OF THE RESULTING INTERPOLYMER EMULSION.
