Abstract

Un método para incorporar un compuesto absorbente de luz de metina que contiene nitrogeno en un poliéster preparado empleando la esterificacion directa de reactivos seleccionados de un ácido dicarboxílico y un diol, donde el método comprende: la reaccion de los reactivos en un reactor de esterificacion, en condiciones suficientes para formar un producto esterificado que comprende por lo menos uno de un éster, un oligomero, o mezcla que tiene un éster y una mezcla de poliéster de bajo peso molecular; la polimerizacion del producto esterificado en un reactor de policondensacion, para formar un poliéster; y la adicion del compuesto absorbente de luz a los productos esterificados, cuando al menos 50% de los grupos carboxi inicialmente presentes en los reactivos se han esterificado. Adicionalmente se decriben artículos donde se utiliza el poliéster con proteccion contra la luz.
