Abstract

LA TEMPERATURA DEL MEDIO DE POLIMERIZACION DEL CLORURO DE VINILO EN LA INTERVENCION DE INICIADORES OLEOSOLUBLES SE REGULA ESENCIALMENTE POR INYECCION DIRECTA Y SE MODULA POR UNA CANTIDAD EFICAZ DE UN INHIBIDOR INORGANICO FUERTE DE LA POLIMERIZACION RADICAL O DE UN PRECURSOR, ELEGIDOS VENTAJOSAMENTE ENTRE EL YODO Y EL MONOXIDO DE NITROGENO, ASI COMO ENTRE LOS YODUROS Y LOS NITRILOS DE LOS METALES ALCALINOS, PRECURSORES RESPECTIVOS DEL YODO Y DEL MONOXIDO DE NITROGENO. EL PROCESO CONDUCE A UNA MEJORA SIGNIFICATIVA DE LA PRODUCTIVIDAD DE LOS REACTORES.
