Abstract

PROCEDIMIENTO DE OBTENCION DE POLIMERIZADOS DE EMULSION EN FORMA DE GRANULOS PULVERULENTOS. CONSISTE EN QUE SE PULVERIZA UNA DISPERSION ACUOSA DE UN POLIMERIZADO DE EMULSION FORMADO PREDOMINANTEMENTE POR MONOMEROS DE ACRILO O DE SU MEZCLA CON ESTIROL (CUYA TEMPERATURA DE VITRIFICACION SEA SUPERIOR A 45JC) EN UNA CORRIENTE DE AIRE CON UNA TEMPERATURA COMPRENDIDA ENTRE 110 Y 250JC PARA FORMAR UN AEROSOL Y SECAR PARA FORMAR GRANULOS DE POLVO DE DIMENSION MEDIA COMPRENDIDA ENTRE 20 Y 50 MM. EL POLVO SECO SE SEPARA DE LA CORRIENTE DE AIRE ANTES DE QUE LOS GRANULOS ALCANCEN LA TEMPERATURA FINAL QUE ES SUPERIOR A LA TEMPERATURA DE VITRIFICACION POR LO QUE SE OBTIENEN AGREGADOS DE PARTICULAS SUELTAS O A LO SUMO DEBILMENTE VITRIFICADAS. DE APLICACION EN LA REDUCCION DEL CONTENIDO DE POLVO FINO EN LA OBTENCION DE POLIMERIZADOS EN FORMA DE GRANULOS.
