Abstract

LA INVENCION SE REFIERE A UN PROCESO PARA CONTROLAR EL CAMBIO DE LA VISCOSIDAD INTRINSECA (IV) Y DE LA TRANSESTERIFICACION, DURANTE EL TRATAMIENTO EN ESTADO SOLIDO DE UNA MEZCLA DE TEREFTALATO DE POLIETILENO (PET) Y DE NAFTALATO DE POLIETILENO (PEN), CON UNA CANTIDAD EFECTIVA DE UN COMPUESTO DE ALQUILEN GLICOL. DICHO PROCEDIMIENTO PERMITE LA PRODUCCION DE UN COPOLIMERO BASADO EN VISCOSIDADES INTRINSECAS INICIAL Y FINAL Y UN NIVEL DE TRANSESTERIFICACION FINAL DEFINIDOS, MEDIANTE LA VARIACION DE LA DURACION DEL TRATAMIENTO EN ESTADO SOLIDO Y/O DE LA CANTIDAD EFECTIVA DE ALQUILEN GLICOL. EN UNA REALIZACION DE LA INVENCION, SE INCORPORA UNA CANTIDAD RELATIVAMENTE MAYOR DE PET POSTCONSUMO (P.EJ. 70 %) CON UN IV DEL ORDEN DE 0,72-0,73 A LA MEZCLA, PARA PROPORCIONAR UN IV FINAL DEL ORDEN DE 0,80-0,85, Y UN NIVEL MODERADO, CONTROLADO, DE TRANSESTERIFICACION. DICHA MEZCLA SE UTILIZA PARA MOLDEAR POR INYECCION UNA CAPA DE REVESTIMIENTO INTERNO DE UNA PREFORMA. EN OTRA REALIZACION DE LA INVENCION, SEFABRICA UN ACABADO DE CUELLO PRACTICAMENTE TRANSPARENTE PARA UNA PREFORMA, A PARTIR DE UNA MEZCLA PEN/PET, QUE TIENE UNA CANTIDAD DE ALQUILEN GLICOL QUE PERMITE UNA TRANSESTERIFICACION SUSTANCIAL, SIN UN INCREMENTO EXCESIVO DE IV.
