Abstract
SE PRESENTA UNA MEJORA PARA HACER DESCENDER LA CARGA ESTATICA ELECTRICA DE UNA RESINA DE CLORURO DE POLIVINIL EN POLVO PARA, DE ESTA MANERA, MEJORAR EL FLUJO DE EL POLVO Y EVITAR UN DESCENSO EN LA DENSIDAD EN BRUTO DEL POLVO PROVOCADO POR LA ELECTRICIDAD ESTATICA. LA MEJORA COMPRENDE LA ADICCION A UNA MEZCLA DE POLIMERIZACION ACUOSA DURANTE EL PROCESO DE POLIMERIZACION, DE UNA CANTIDAD ESPECIFICADA DE UNA DISPERSION ACUOSA QUE CONTENGA UNA SAL DE UN ACIDO CARBOXILICO DE CADENA LARGA CON UN METAL DIVALENTE Y UN ESTER DE SORBITAN CON UN ACIDO CARBOXILICO DE CADENA LARGA EN UNA ESPECIFICA PROPORCION Y EN UNA CONCENTRACION ESPECIFICA, EN UN PUNTO EN EL QUE LA CONVERSION DEL MONOMERO A POLIMERO SEA DE AL MENOS EL 70 %.
