Abstract

LA INVENCION PROPORCIONA UN PROCESO PARA PREPOLIMERIZAR CATALIZADORES DE POLIMERIZACION DE OLEOFINAS, Y UN PROCESO PARA AUMENTAR LA EFICACIA DE CATALIZADORES DE POLIMERIZACION DE OLEOFINA PREPOLIMERIZADOS. EN UN PROCESO DE ESTA INVENCION, SE AÑADE UN MONOMERO DE OLEOFINA A UNA CORRIENTE DE SOPORTE DE FLUIDO, CONTENIENDO UN CATALIZADOR DE POLIMERIZACION DE OLEOFINA. LA CORRIENTE DE SOPORTE CONTENIENDO EL MONOMERO Y EL CATALIZADOR SE PASA POR UN REACTOR TUBULAR ALARGADO, A UN RITMO DE FLUJO SUFICIENTE PARA PROPORCIONAR UN TIEMPO DE PERMANENCIA EN EL REACTOR TUBULAR DE MENOS DE 1 MINUTO, Y EN CONDICIONES TERMICAS PARA PREPOLIMERIZAR EL CATALIZADOR DENTRO DEL REACTOR TUBULAR SIN OBTURAR O ATASCAR EL REACTOR. EN OTRO PROCESO DE ESTA INVENCION, SE CONTACTA UN CATALIZADOR PREPOLIMERIZADO CON COCATALIZADOR O UNA MEZCLA DE COCATALIZADOR, Y UN DONANTE DE ELECTRONES (ATOMO QUE PROPORCIONA ELECTRONES CON ENLACE SEMIPOLAR), CON ANTERIORIDAD A LA INTRODUCCION DEL CATALIZADOR EN LA ZONA DE REACCION DE POLIMERIZACION.
