Title (EN) PROCESS FOR MANUFACTURING POLYESTER RESINS
(FR) PROCÉDÉ DE FABRICATION DE RÉSINES DE POLYESTER
Abstract:
(EN) The present invention is directed at a process for crystallizing non-solid state polymerized polyester resins to improve the extrusion of such resins to manufacture articles using standard screws designed for solid state polymerized resins, and to reduce the amount of oligomers in such articles. The non-solid state polyester polymerization polyester process which includes a final crystallizer process that does not increase the IV of the resin by more than about 0.02 dl/g.
(FR) La présente invention concerne un procédé de cristallisation de résines de polyester polymérisées à l'état non solide permettant d'améliorer l'extrusion de telles résines pour fabriquer des articles à l'aide de vis standard conçues pour des résines polymérisées à l'état solide, et permettant de réduire la quantité d'oligomères dans de tels articles. Le procédé de polymérisation de polyester à l'état non solide comprend un processus de cristallisation final qui n'augmente pas l'IV de la résine de plus d'environ 0,02 dl/g.
