Abstract

Cette invention concenre la synthèse de polyphtalamides semi-cristallins (c'est-à-dire contenant des unités monomères d'acide téréphtalique et d'hexaméthylène diamine) par extrusion réactive d'oligomère de téréphtalamide d'hexaméthylène ou de l'oligomère d'un autre copolymère riche en 6T, avec des polyamides semi-cristallins ou amorphes à bas point de fusion. Ce procédé est particulièrement utile du fait qu'il est fondé sur l'utilisation d'autoclaves à agitation pour effectuer la synthèse de l'oligomère 6T et des polyamides semi-cristallins ou amorphes qui sont ensuite combinés dans une extrudeuse à deux vis équipée pour extraire les substances volatiles de l'eau de réaction. Le procédé de cette invention peut également être utilisé pour modifier des polyamides semi-cristallins ou amorphes qui existent déjà (mais pas nécessairement des phtalamides) avec de faibles taux de 6T.
