Abstract

Una composicion de poliéster, estabilizada contra la formacion de contaminantes aldehídicos durante el proceso de fundido de dicho poliéster, que comprende(a) un poliéster, y (b) una cantidad estabilizadora efectiva de un segundo polímero que sesele cciona entre el grupo que consiste en alcohol polivinílico, uncopolímero de etileno/alcohol vinílico y un alcohol polihídrico de la formula E-(OH)n en donde n es 2 a 4000, y E es una porcion alifática, cicloalifática,aromática o un mono-, di-o poli -sacárido; y si el componente (b) es alcohol polivinílico o un copolímero de etileno/alcohol vinílico, la cantidad decomponente (b) es 0,005 a 0,075% en peso de la composicion estabilizada que es adecuada para cuando es sometida a extrusionpara mezc lado exhibe un contenidode acetaldehído residual más bajo que el PET solo cuando es tratado en forma similar. Sirve para cualquier poliéster utilizado en la fabricacion de botellas oenvases que a su vez se utiliza para almacenar materialesde consumo , especialmente alimento, bebidas y más especialmente agua. Método y uso para evitar laformacion de dichos contaminantes.
