Abstract
METODO DE PREPARACION DE POLIMEROS ANIONICOS Y NO IONICOS DE PESO MOLECULAR ELEVADO, SOLUBLES EN AGUA, CON UN CONTENIDO EN SOLIDOS DEL 30-40%, MEDIANTE POLIMERIZACION EN EMULSION. COMPRENDE LA POLIMERIZACION EN EMULSION CON UN CONTENIDO EN SOLIDOS POLIMERIZABLES ENTRE 2 Y 20%; ADICION, DURANTE EL PROCESO DE POLIMERIZACION, DE AGENTES TENSOACTIVOS COPOLIMERIZABLES, TALES COMO DERIVADOS VINILICOS CON DIFERENTES GRADOS DE OXIETILENACION O DERIVADOS VINILICOS SULFONADOS EN CONCENTRACIONES COMPRENDIDAS ENTRE 0,1 Y 3%; Y A CONTINUACION AJUSTAR EL CONTENIDO EN MATERIAL POLIMERICO A CONCENTRACIONES DEL 30 AL 40% POR DESTILACION AZEOTROPICA DEL EXCESO DE DISOLVENTE. ESTOS POLIMEROS TIENEN APLICACIONES COMO FLOCULANTES EN AGUAS DE PROCESO, INDUSTRIALES Y MUNICIPALES Y PARA LA INDUSTRIA MINERA; COMO RECUPERADORES DE ACEITES, DE FIBRAS DE PAPEL, CARTON Y FIBRO-CEMENTO, DESHIDRATACION DE LODOS; Y RETENEDORES DE FIBRAS.
