Abstract

PROCEDIMIENTO PARA LA OBTENCION DE POLIMERIZADOS PULVERULENTOS DEL POLIETILENO, CON UNA GRANULOMETRIA INFERIOR A 200 UM. SE PREPARA UNA SUSPENSION DE UN POLIMERIZADO DE FRANCCION ORDINARIA DEL ETILENO; SE CALIENTA LA SUSPENSION A UNA TEMPERATURA POR ENCIMA DEL MARGEN DE REBLANDECIMIENTO DEL POLIMERIZADO; SE PROCEDE AL DESDOBLAMIENTO DEL ESTER CONTENIDO EN EL POLIMERIZADO MIXTO, CON AYUDA DE CATALIZADORES ALCALINOS O ACIDOS; APARTE DE LA SUSPENSION SE EMPLEAN CETONAS ALIFATICAS, CON 3 A 10 ATOMOS DE CARBONO, AISLADAS Y MEZCLADAS; EN EL CALENTAMIENTO SE ESPONJA EL POLIMERIZADO DE GRANO GRUESO Y SE DESCOMPONE, EN LA MEZCLA, CON EL AGENTE DE SUSPENSION AL ENFRIARSE EN PULVERIZADO FINO. DE APLICACION COMO MATERIAL DE REVESTIMENTO.
