Abstract

PROCEDIMIENTO PARA LA SINTESIS DE POLIMEROS DE ALTO PESO MOLECULAR POR POLIMERIZACION DE MONOMEROS MONOETILENICAMENTE INSATURADOS SOLUBLES EN AGUA Y EN CASO DADO RETICULANTES Y OPCIONALMENTE MONOMEROS MONOETILENICAMENTE INSATURADOS INSOLUBLES EN AGUA EN UNA DISOLUCION ACUOSA Y EN PRESENCIA DE INICIADORES DE POLIMERIZACION EN UN REACTOR CON FORMA DE TUBO, QUE EN EL EXTREMO POSEE UN ESTRECHAMIENTO CONICO. LA RELACION ENTRE EL DIAMETRO DEL REACTOR (D1) Y EL DIAMETRO DEL EXTREMO CON EL ESTRECHAMIENTO CONICO (D2) ES DE 2:1 HASTA 25:1, Y EL ANGULO ENTRE D1 AL PRINCIPIO DEL ESTRECHAMIENTO CONICO Y LA PARED INTERNA DEL CONO ES MAYOR DE 45 Y MENOR DE 90 GRADOS. SE SACA LA MEZCLA DE REACCION DEL REACTOR POR PRESION CON UN GAS INERTE.
