Abstract
UN AGENTE PARA PREVENIR LAS INCRUSTACIONES EN POLIMEROS A UTILIZAR EN LA POLIMERIZACION DE UN MONOMERO QUE TIENE UN DOBLE ENLACE NO SATURADO ETILENICALMENTE, Y QUE INCLUYE UNA SOLUCION ALCALINA QUE CONTIENE (A) UN PRODUCTO DE CONDENSACION QUE TIENE UN PESO MOLECULAR DE 400 A 50.000 OBTENIDO MEDIANTE LA CONDENSACION DE UN COMPUESTO DE QUINONA. ESTE AGENTE SE APLICA A LAS SUPERFICIES DE LA PARED INTERIOR DE UN RECIPIENTE DE POLIMERIZACION Y SE DEJA SECAR PARA FORMAR UN REVESTIMIENTO. TAL RECIPIENTE ES EFECTIVO PARA PREVENIR LA DEPOSICION DE INCRUSTACIONES EN EL POLIMERO NO SOLO EN LAS AREAS DISPUESTAS EN LA REGION DE LA FASE LIQUIDA SINO TAMBIEN EN LAS AREAS DE ALREDEDOR DE LA INTERFAZ ENTRE LAS FASES DE GAS Y LIQUIDO DEL RECIPIENTE Y ES UTIL PARA LA PRODUCCION DE UN POLIMERO QUE TENGA POCOS OJOS DE PESCADO Y MUCHA BLANCURA CUANDO A PARTIR DE EL SE FORMAN LAMINAS O SIMILARES.
