Stable aqueous dispersions of ethylene aminoalkyl acrylate copolymers
Abstract
Abstract STABLE, AQUEOUS, CATIONIC POLYELECTROLYTE DISPERSIONS ARE PROVIDED IN WHICH COPOLYMERS OF ETHYLENE AND SELECTED AMINOALKYL ACRYLATES AND METHACRYLATES ARE SELFDISPERSED IN WATER WITH ACIDS HAVING A DISSOCIATION CONSTANT GREATER THAN 10**-5. SUCH DISPERSIONS ARE PREPARED BY STIRRING WATER, A COPOLYMER AND AN ACID IN A VESSEL, PREFERABLY AT A TEMPERATURE ABOVE THE MELTING POINT OF THE COPOLYMER WHEN THE COPOLYMER IS OF HIGH MOLECULAR WEIGHT AND ETHYLENE CONTENT. WHILE THERE ARE A NUMBER OF USES FOR SUCH DISPERSIONS, PARTICULARLY PREFERRED USES ARE: (1) CURED, ULTRA-THIN COATINGS ON METALLIC SBSTRATES, PARTICULARLY ALUMINUM, (2) AS ACID DYEABLE COATINGS ON CELLULOSIC SUBSTRATES SUCH AS PAPER, AND (3) AS FLOCCULATING AGENTS FOR REMOVING SUSPENDED MATTER FROM WATER.
