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).
