Abstract
Una composicion de polímeros de poliéster que contiene polímeros de poliéster tales como polímeros que poseen unidades repetitivas de etilen tereftalato, átomos de aluminio en una cantidad de al menos 3 ppm en base al peso del polímero, teniendo los polímeros de poliéster una It.V. de al menos 0,72 dL/g obtenida a travpes de una polimerizacion en fase fundida y un nivel de acetaldehído residual de 10ppm o menor. También se proveen composiciones de polímeros de poliéster que contienen polímeros de poliéster y: (i) átomos de aluminio, (ii) átomos de metal alcalino térreo o átomos de metal alcalino o residuos de compuesto alcalino, y (iii) un desactivador de catalizador tal como un compuesto de fosforo. El compuesto de fosforo se adiciona al fundido de poliéster ya sea más tarde en la policondensacion o luego de refundir un polímero de poliéster solido. El polímero de poliéster exhibe buen brillo L*, claridad, y bajos niveles de acetaldehído generado luego del fundido.A composition of polyester polymers containing polyester polymers such as polymers having repetitive units of ethylene terephthalate, aluminum atoms in an amount of at least 3 ppm based on the weight of the polymer, the polyester polymers having an It.V. of at least 0.72 dL / g obtained through a melt phase polymerization and a residual acetaldehyde level of 10ppm or less. Compositions of polyester polymers containing polyester polymers and: (i) aluminum atoms, (ii) alkaline earth metal atoms or alkali metal atoms or alkaline compound residues, and (iii) such a catalyst deactivator are also provided. as a phosphorus compound. The phosphorus compound is added to the polyester melt either later in the polycondensation or after recasting a solid polyester polymer. The polyester polymer exhibits good L * brightness, clarity, and low levels of acetaldehyde generated after melting.
