Abstract
METODO PARA PREVENIR LA DEPOSICION DE ESCALAS DE POLIMEROS DURANTE LA POLIMERIZACION DE UN MONOMERO CON UN LAZO ETILENICAMENTE DOBLE EN UN RECIPIENTE DE POLIMERIZACION, QUE COMPRENDE EL PASO DE LLEVAR A CABO DICHA POLIMERIZACION EN UN RECIPIENTE DE POLIMERIZACION EN EL CUAL LA SUPERFICIE DE SU PARED INTERNA TIENE UNA CAPA PROTECTORA QUE INCLUYE UN POLISACARIDO SOLUBLE EN AGUA; Y UN AGENTE PREVENTIVO DE ESCALA DE POLIMEROS QUE COMPRENDE POLISACARIDOS. UTILIZANDO EL METODO O AGENTE, SE PUEDE PREVENIR EFICAZMENTE LA DEPOSICION DE ESCALAS DE POLIMEROS; ADEMAS , SE PUEDEN PREPARAR POLIMEROS CON UN ALTO GRADO DE BLANCURA. ASIMISMO, EL AGENTE QUE IMPIDE LA FORMACION DE ESCALAS UTILIZADO NO TIENE TOXICIDAD ALGUNA Y ES MUY SEGURO.
