Abstract

El presente invento suministra un proceso que comprende los pasosde:a) reaccionando por fundición por lo menos un glicol y por lo menos un ácido dicarboxílico para formar un poliéster con un IhV de por lo menos 0.5 dl/g, en donde dicho por lo menos un glicol es seleccionado del grupo consistente en glicoles con hasta 10 átomos de carbono y mezclas de los mismos y dicho dicarboxílico es seleccionado entre el grupo consistente en ácidos alquil dicarboxílicos con 2 a 16 átomos de carbono, ácidos aril dicarboxílicos con 8 a 16 átomos de carbono y mezclas de los mismos; y b) formando dicho poliéster en artículos contorneados directamente del pasa a. Por consiguiente, el presente invento suministra un proceso directo de fundido a moldeado para formar artículos de poliéster.The present invention provides a process comprising the steps of: a) melting at least one glycol and at least one dicarboxylic acid to form a polyester with an IhV of at least 0.5 dl / g, where said at least a glycol is selected from the group consisting of glycols with up to 10 carbon atoms and mixtures thereof and said dicarboxylic acid is selected from the group consisting of alkyl dicarboxylic acids with 2 to 16 carbon atoms, aryl dicarboxylic acids with 8 to 16 carbon atoms carbon and mixtures thereof; and b) forming said polyester into contoured articles directly from passage a. Accordingly, the present invention provides a direct melt-to-cast process to form polyester articles.
