Abstract

PROCESOS PARA PRODUCIR POLICARBONATO POR POLIMERIZACION EN FASE SOLIDA QUE SIMPLIFICAN LA CRISTALIZACION PREVIA A LA POLIMERIZACION EN FASE SOLIDA PERMITIENDO ASI UN MAYOR ACORTAMIENTO EN EL TIEMPO DE TRATAMIENTO. UN PROCESO PARA PRODUCIR POLICARBONATO SE CARACTERIZA EN QUE UN PREPOLIMERO DE POLICARBONATO AMORFO PREPARADO POR TRANSESTERIFICACION DE UN COMPUESTO DIHIDROXI AROMATICO CON UN DIESTER DE ACIDO CARBONICO SE PREPOLIMERIZA EN FASE SOLIDA BAJO UNA ATMOSFERA QUE CONTIENE SOLVENTE HINCHADO GASEOSO MIENTRAS SE MANTIENE EL PREPOLIMERO EN ESTADO FLUIDO. OTRO PROCESO PARA PRODUCIR POLICARBONATO SE CARACTERIZA EN QUE UNA MEZCLA QUE INCLUYE UN PREPOLIMERO DE POLICARBONATO AMORFO PREPARADO POR TRANSESTERIFICACION DE UN COMPUESTO DIHIDROXI AROMATICO CON UN DIESTER DE ACIDO CARBONICO Y UN PREPOLIMERO CARBONATO QUE HA SUFRIDO CRISTALIZACION SE PREPOLIMERIZA EN FASE SOLIDA BAJO UNA ATMOSFERA QUE CONTIENE SOLVENTE HINCHADO GASEOSO.
