Abstract
SE DESCRIBE UN AGENTE PREVENTIVO DE ESCALA POLIMERICA PARA UTILIZAR EN LA POLIMERIZACION DE UN MONOMERO QUE TIENE UN DOBLE ENLACE ETILENICAMENTE INSATURADO, QUE COMPRENDE UNA SOLUCION ALCALINA QUE CONTIENE (A) UN PRODUCTO DE CONDENSACION DE (A-1) UN COMPUESTO HIDROXONAFTALENO Y (A-2) UN COMPUESTO ALDEHIDO, Y (B) UN COLOIDE INORGANICO. EL AGENTE SE UTILIZA PARA FORMAR UN REVESTIMIENTO SOBRE LA PARED INTERNA, ETC. DE UN RECIPIENTE DE POLIMERIZACION, EL CUAL ES EFECTIVO PARA PREVENIR LA DEPOSICION DE ESCALA POLIMERICA, NO SOLO EN LA ZONA DE FASE-LIQUIDA SINO TAMBIEN EN EL VACIO DE LA INTERFASE ENTRE LAS FASES LIQUIDA Y GASEOSA, Y ES UTIL PARA PRODUCIR UN POLIMERO QUE EXHIBE MUY POCOS OJOS DE PEZ Y BUENA BLANCURA FORMADA DENTRO DE LAS HOJAS O SIMILARES
