Abstract

UN POLIMERO DE CLORURO DE VINILO SE PREPARA POR POLIMERIZACION EN SUSPENSION DE CLORURO DE VINILO MONOMERICO O UNA MEZCLA DE CLORURO DE VINILO Y OTRO MONOMERO EN UN MEDIO ACUOSO MIENTRAS SE AGITA LA SUSPENSION. UN PRIMER ALCOHOL POLIVINILO PARCIALMENTE SAPONIFICADO QUE TIENE UN GRADO DE SAPONIFICACION DEL 60 .000 SE AÑADE COMO ESTABILIZADOR DE LA SUSPENSION AL PRINCIPIO DE LA POLIMERIZACION, Y UN SEGUNDO ALCOHOL POLIVINILO PARCIALMENTE SAPONIFICADO QUE TIENE UN GRADO DE SAPONIFICACION DEL 75% DE AGITACION SE CONTROLA A 80 DE EL PRINCIPIO DE LA POLIMERIZACION HASTA UN CONVERSION DEL 20% AL 50% Y A 130 HASTA EL ACABADO DE LA POLIMERIZACION. EL POLIMERO DE CLORURO DE VINILO RESULTANTE ES DE CALIDAD DEMOSTRADA POR UNA ALTA DENSIDAD DE VOLUMEN Y UN FLUJO LIBRE MEJORADO, LA RETIRAD DEL MONOMERO, LA GELACION Y LA ABSORCION PLASTIFICADORA ASI COMO UN MINIMO OJO DE PEZ. SE MINIMIZA LA FORMACION DE ESCAMA SOBRE LA PARED DEL REACTOR.
