Abstract: La invencion se relaciona a un metodo para producir mezclas de polimero, que son adecuadas para el uso como auxiliadores de filtro, de poliestireno y polivinilpirrolidonas insolubles en agua reticuladas procesando los componentes en un extrusor. La invencion se caracteriza porque el poliestireno se funde en un extrusor, entonces se mezcla con polivinilpirrolidona, y se agrega agua a la mezcla de los componente que tienen 0.1 a 10% en peso con respecto a la cantidad total de poliestireno y polimero de palomitas de maiz, en donde la mezcla se extruye y pulveriza.
