Abstract

PROCEDIMIENTO PARA LA PREPARACION DE UN POLIMERO DE CLORURO DE VINILO. COMPRENDE LAS FASES DE CARGA DE UN INICIADOR DE POLIMERIZACION POR UN PASO DE CARGA QUE COMUNICA CON EL INTERIOR DEL RECIPIENTE DE POLIMERIZACION Y POLIMERIZAR CLORURO DE VINILO O UNA MEZCLA DE MONOMEROS DE VINILO CONTENIENDO CLORURO DE VINILO EN UN MEDIO ACUOSO, DE FORMA QUE, DESPUES DE QUE EL INICIADOR DE POLIMERIZACION HA SIDO CARGADO EN EL RECIPIENTE DE POLIMERIZACION, DICHO PASO DE CARGA ES LAVADO CON UN FLUIDO DE LIMPIEZA QUE CONTIENE UN INHIBIDOR DE LA POLIMERIZACION. ESTE PROCEDIMIENTO PUEDE IMPEDIR DE MANERA EFECTIVA LA FORMACION DE ESCAMAS EN EL PASO DE CARGA, PRODUCIENDO UN POLIMERO DE CLORURO DE VINILO DE ALTA CALIDAD.
