Abstract

UN AGENTE QUE PREVIENE LAS INCRUSTACIONES EN POLIMEROS PARA UTILIZARLO EN LA POLIMERIZACION DE UN MONOMERO QUE TIENE UN ENLACE DOBLE NO SATURADO ETILENICALMENTE, QUE COMPRENDE UNA SOLUCION ALCALINA QUE CONTIENEN UN PRODUCTO DE CONDENSACION DE (A) UN COMPUESTO DE AMINA AROMATICA Y (B) UN COMPUESTO DE QUINONA. ESTE AGENTE SE UTILIZA PARA LA FORMACION DE UN REVESTIMIENTO EN LA PARED INTERIOR, ETC. DE UN RECIPIENTE DE POLIMERIZACION. TAL RECIPIENTE ES EFECTIVO PARA PREVENIR LA DEPOSICION DE INCRUSTACIONES EN POLIMEROS Y ES UTIL PARA LA PRODUCCION DE UN POLIMERO QUE PRESENTE MUY POCOS OJOS DE PESCADO Y UNA GRAN BLANCURA CUANDO SE FORMAN LAMINAS A PARTIR DE EL O SIMILARES.
