Abstract

UN PROCEDIMIENTO DE PREPARACION DE UN POLIMERO DE CLIRURO DE VINILO EN UNA VASIJA DE POLIMERIZACION, QUE COMPRENDE LAS SIGUIENTES ETAPAS: CARGAR UN INICIADOR DE POLIMERIZACION A TRAVES DE UN CONDUCTO DE CARGA QUE COMUNICA CON EL INTERIOR DE LA VASIJA DE POLIMERIZACION; Y POLIMERIZAR EL CLORURO DE VINILO O UNA MEZCLA DE MONOMEROS VINILICOS QUE CONTIENE CLORURO DE VINILO EN UN MEDIO ACUOSO, DONDE, DESPUES DE HABER CARGADO EN LA VASIJA DE POLIMERIZACION EL CITADO INICIADOR DE LA POLIMERIZACION, EL CONDUCTO DE CARGA CITADO SE CALIENTA EXTERNAMENTE. ESTE PROCEDIMIENTO PUEDE EVITAR LA FORMACION DE INCRUSTACIONES EN EL CONDUCTO DE CARGA Y PRODUCIR UN POLIMERO DE CLORURO DE VINILO DE GRAN CALIDAD.
