Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO PARA LA ELABORACION DE COPOLIESTERES LINEALES, CONTENIENDO UNIDADES {OE} - ACIDO HIDROXICARBOXILICO A BASE DE POLIESTER, QUE MUESTRAN AL MENOS 90 % MOL DE UNIDADES TEREFTALATO DE POLIETILENO Y CONTIENEN LOS CATALIZADORES CONOCIDOS EN LAS CANTIDADES HABITUALES. LA COLADA DE POLIESTER SE APLICA EN UN SISTEMA CERRADO CONTRA INTERCAMBIO DE GAS Y BAJO ALTA PRESION COMO PRESION DE VAPOR-LACTONA, QUE MUESTRA O BIEN REACTORES O EXTRUSIONADORES, HASTA UN 10 % MOL, CON REFERENCIA A LA COLADA ELABORADA, AL MENOS DE UN COMPUESTO DEL GRUPO DE LACTONA, ASI COMO A ELECCION SE AÑADEN OTROS ADITIVOS, QUE SE MEZCLAN DE MANERA INTENSIVA CON LA COLADA. EL COPOLIESTER ASI OBTENIDO SE GRANULA DESPUES DE UN TIEMPO DE PERMANENCIA TOTAL POR BAJO DE 30 MIN. Y UNA TEMPERATURA EN LA ZONA DESDE 265 HASTA 310 STERIORMENTE, CON TRATAMIENTO QUE TIENE LUGAR A CONTINUACION. EL COPOLIESTER CONTIENE LA MISMA VISCOSIDAD CON EL POLIESTER DE PARTIDA Y DISPONE DE UNIDADES {OE} - ACIDO HIDROXICARBOXILICO DISTRIBUIDAS DE MANERA ESTADISTICA EN LA CADENA DE POLIMERO.
