Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO PARA REALIZAR REACCIONES DE POLICONDENSACION, SEGUN EL CUAL LA POLICONDENSACION DE UN EDUCTO MONOMERICO SE REALIZA CON UN SUMINISTRO EXTERIOR DE CALOR EN UNA COMBINACION DE UN REACTOR DE AL MENOS DOS ETAPAS, QUE COMPRENDE UN PRE - REACTOR Y UN REACTOR DE ALTA VISCOSIDAD, RETIRANDOSE POR EVAPORACION LOS PRODUCTOS DE LA ESCISION DE BAJO PESO MOLECULAR. EN EL PRE REACTOR, EL PRODUCTO DE REACCION SE CONCENTRA EN UN PRODUCTO VISCOSO DE PARTIDA, Y DICHO PRODUCTO VISCOSO DE PARTIDA SE HACE A CONTINUACION REACCIONAR PLENAMENTE CONVIRTIENDOLO EN UN PRODUCTO DE POLICONDENSACION EN EL REACTOR DE ALTA VISCOSIDAD, POR ADICION DE ENERGIA TERMICA Y MECANICA DURANTE UN PERIODO DE 20 SEGUNDOS A 60 MINUTOS.
