Abstract
UN AGENTE PREVENTIVO CONTRA ESCAMAS POLIMERAS PARA USAR EN POLIMERIZACION DE UN MONOMERO QUE TIENE UN DOBLE ENLACE NO SATURADO ETILENICAMENTE, CONTENIENDO UN PRODUCTO DE CONDENSACION OBTENIDO POR CONDENSACION DE (A) UN COMPUESTO DE DIAMINA ALIFATICA, Y (B) UN COMPUESTO DE QUINONA, EN UN MEDIO ACUOSO. DONDE EL MONOMERO SE POLIMERIZA EN UNA VASIJA DE POLIMERIZACION QUE TIENE SOBRE LA SUPERFICIE DE SUS PAREDES INTERNAS UNA CUBIERTA CONTENIENDO EL AGENTE PREVENTIVO. LA DEPOSICION DE ESCAMAS DEL POLIMERO SE PUEDE PREVENIR EFECTIVAMENTE, NO SOLO EN LA PORCION DE LA FASE LIQUIDA EN LA VASIJA DE POLIMERIZACION, SINO TAMBIEN EN LA PROXIMIDAD DE LA ENTREFASE DE LA PORCION DE FASE GASEOSA Y DE LA PORCION DE FASE LIQUIDA, DE MODO QUE EL POLIMERO ASI OBTENIDO PROVEE UN ARTICULO MOLDEADO CON POCOS OJOS DE PEZ Y REDUCIDA COLORACION INICIAL, CUANDO EL POLIMERO SE MOLDEA EN LAMINAS O FORMAS SIMILARES.
