Abstract
EL PROCEDIMIENTO CONSISTE EN LA AGLOMERACION DE PARTICULAS FINAS DE POLIMERO SUPERABSORBENTE REALIZADO POR LA INTRODUCCION DE UNA SOLUCION ACUOSA DE MONOMERO EN UN CALDO DE POLIMERO ACUOSO DISPERSO EN EL SENO DE UN LIQUIDO HIDROCARBONADO, OPERANDOSE ESTA INTRODUCCION DIRECTAMENTE A LA TEMPERATURA Y EN CONDICIONES DE POLIMERIZACION DEL MONOMERO. SE OBTIENE ASI CON UN RENDIMIENTO MUY BUENO UN PRODUCTO SUPERABSORBENTE EN FORMA DE AGREGADOS DE PARTICULAS CUYO TRANSITO A 100 MICROMETROS ES INFERIOR A 1%.
