Abstract

La presente es un método para incorporar eficientemente un absorbedor de UV en una resina de poliéster. El método incluye formar una mezcla de reacción que comprende un componente diol, un componente seleccionado del grupo que consiste en ácidos dicarboxílicos, derivados de ácido dicarboxílico, y mezclas de los mismos, un compuesto que contiene antimonio, un compuesto que contiene fósforo, un compuesto que contiene metal, y un absorbedor de UV. La mezcla de reacción se polimeriza en un sistema de reacción de policondensación. En otra realización de la presente, se agrega el absorbedor de UV mientras los productos de reacción de un reactor son transferidos al reactor siguiente en el sistema de reacción de policondensación. También se describe una composición de poliéster que tiene el absorbedor de UV incorporado a la misma. Reivindicación 1: Un método para incorporar un absorbedor de UV a una resina de poliéster, donde dicho método comprende: a) formar una mezcla de reacción sustancialmente libre de un compuesto catalítico de intercambio de éster que contiene titanio, y que comprende combinar: un diol, un componente diácido seleccionado del grupo que consiste en ácidos dicarboxílicos, derivados de ácido dicarboxílico, y mezclas de los mismos, un compuesto que contiene antimonio en una cantidad de menos de 0,1% del peso total de la mezcla de reacción, un compuesto que contiene fósforo presente en una cantidad de menos de aproximadamente 0,1% del peso total de la mezcla de reacción, un compuesto que contiene metal seleccionado del grupo que consiste en compuestos que contiene zinc, compuestos que contienen manganeso, presentes en una cantidad de desde aproximadamente 10ppm hasta aproximadamente 300ppm, y un compuesto absorbedor de UV en el cual dicho compuesto absorbedor de UV comprende por lo menos un radical 4-oxibencilideno de fórmula (1) en la cual X es H de hasta dos porciones seleccionadas del grupo que consiste en hidroxi, alquilo C1-6, alcoxi C1-6 y halógeno, y donde el compuesto absorbedor de UV incluye un grupo reactivo de poliéster, y b) polimerizar la mezcla de reacción en el sistema de reacción de policondensación, donde dicho sistema de reacción de policondensación tiene una primera cámara de reacción, una última cámara de reacción, y una o más cámaras de reacción intermedias entre la primera cámara de reacción y la última cámara de reacción, donde el sistema de reacción funciona en series de manera que la mezcla de reacción se polimeriza progresivamente en la primera de cámara de reacción, la una o más reacciones intermedias, y la última cámara de reacción.
