Abstract
SE DESCRIBEN MAS PARTICULAS DE MATERIAL POLIMERICO LINDIABLE QUE SON CONVERTIDAS EN UNA MASA DE GEL MEDIANTE LA ABSORCION EN UNA DISOLUCION ACUOSA DE UN AGENTE ENLAZANTE (ENTRE LAS PARTICULAS MAS FINAS); EL ENLACE OCURRE ENTRE DICHO AGENTE Y LOS GRUPOS PENDIENTES DEL POLIMETO Y TRAS ESTO LA MASA ES SECADA Y DESMENUZADA. EL POLIMETO ES PREFERENTEMENTE UN POLIMERO DE ACIRLATO DE SODIO UNIDO TRANSVERSALMENTE Y EL AGENTE ENLAZANTE ES PREFERENTEMENTE UN ESTER GLICIDIL O UN AGENTE DE ENLACE TRANSVERSAL DE SILANO. EL PRODUCTO ES NUEVO Y COMPRENDE UNA ESTRUCTURA POLIMERICA FORMADA POR ZONAS EN LAS CUALES, EL POLIMERO ESTA SUSTANCIALMENTE LIBRE DE ENLACES TRANSVERSALES ENTRE LOS GRUPOS PENDIENTES, Y LAS ZONAS ESTAN INTERCONECTADAS POR DICHOS ENLACES A TRAVES DE LOS GRUPOS PENDIENTES
