Title (EN) A PROCESS FOR POLYMERIZING CYCLIC OLIGOMERS OF POLYAMIDES
(FR) PROCÉDÉ DE POLYMÉRISATION D'OLIGOMÈRES CYCLIQUES DE POLYAMIDES
Abstract:
(EN) A process for production of high molecular weight polyamide polymers, such as 6/66 copolymers, using a reactant stream that includes at least one lactam and cyclic oligomers. The stream is reacted with at least one diamine at an elevated temperature to ring-open the cyclic oligomers to produce amide pre-polymers that are end-capped with amine groups. The pre-polymers are then reacted with at least one diacid at an elevated temperature to form polyamide 6/66 copolymers. The cyclic oligomers may be formed as by-products during standard polymerization of polyamide polymers from monomers such as caprolactam, hexamethylene diamine and adipic acid.
(FR) L'invention concerne un procédé de production de polymères de polyamides à grande masse moléculaire, tels que des polymères de 6/66, par utilisation d'un flux de réactifs qui contient au moins un lactame et des oligomères cycliques. Le flux est mis à réagir avec au moins une diamine à haute température pour décycliser les oligomères cycliques dans le but de produire des prépolymères d'amides qui sont coiffés en bout par des groupes amine. Les prépolymères sont ensuite mis à réagir avec au moins un diacide à une haute température pour former des copolymères de polyamides 6/66. Les oligomères cycliques peuvent être formés en tant que sous-produits au cours d'une polymérisation standard de polymères de polyamides à partir de monomères tels que le caprolactame, l'hexaméthylènediamine et l'acide adipique.
