Abstract

LA INVENCION CONCIERNE A UN MEDIO DE ABSORCION EN FORMA DE POLVO PARA LIQUIDOS ACUOSOS A BASE DE UN POLIMERO EN POLVO SOLUBLE EN AGUA CON AL MENOS 0,2 EQUIVALENTES DE GRUPOS CARBOXILOS POR CADA 100 PARTES EN PESO, QUE SE NEUTRALIZAN HASTA UN 50 A 99, PERO PREFERENTEMENTE AL MENOS HASTA EL 80% EN MOLES. EL MEDIO DE ABSORCION SE PUEDE OBTENER MEDIANTE EL TRATAMIENTO DE POLIMEROS SOLUBLES EN AGUA, QUE CONTIENEN GRUPOS CARBOXILOS CON UNA SOLUCION DE UN ESTER DE N A) ALANINA O SUS PRODUCTOS DE POLICONDENSACION. COMO DISOLVENTES PARA EL TRATAMIENTO SIRVE EL AGUA QUE CONTIENE DILUYENTES ORGANICOS MISCIBLES CON AGUA EVAPORADOS AL CALENTAR LA MEZCLA O QUE NO SE EVAPORAN, ES DECIR DILUYENTES RESIDUALES EN POLIMEROS.
