Abstract

Un proceso para producir artículos moldeados que comprende los pasos de: a) hacer reaccionar en fusión por lo menos un glicol y por lo menos un ácidodicarboxílico para formar un poliéster que tenga una V.I. de por lo menos 0,5 dl/g, estando porlo menos dicho glicol seleccionado a partir del grupo queconsiste en glicoles que tienen hasta 10 átomos de carbono y mezclas de los mismos, y estando dicho ácido dicarboxílico seleccionado a partir del grupoque consiste en ácidos dicarboxílicosalquílicos que tienen de 2 a 16 átomos de carbono, ácidos dicarboxílicos arílicos que tienen de 8 a 16 átomos decarbono y mezclas de los mismos; y b) formar artículos moldeados con dicho poliéster directamente a partir del paso (a).A process for producing molded articles comprising the steps of: a) melt reacting at least one glycol and at least one carboxylic acid to form a polyester having an IV. of at least 0.5 dl / g, at least said glycol being selected from the group consisting of glycols having up to 10 carbon atoms and mixtures thereof, and said dicarboxylic acid being selected from the group consisting of acids alkyl dicarboxylic acids having 2 to 16 carbon atoms, aryl dicarboxylic acids having 8 to 16 carbon atoms, and mixtures thereof; and b) forming molded articles with said polyester directly from step (a).
