Abstract

El objeto de la invencion es proveer un agente anticrustacion para revestir los reactores de polimerizacion para monomeros, de los tipos líquidos, obtenidos por medio de la condensacion de naftoles con un producto entrelazador aldehídico, caracterizado porque: para obtener el condensado se usa un hidrosulfito; contiene hidrosulfito y/o radicales bisulfito y/o bisulfito; el condensado está hecho de tal manera que en ausencia de oxígeno está en forma de líquido de color transparente claro.
