Abstract

La présente invention concerne un procédé de préparation d'une composition de résine de mélange de polyéthercétonecétone (ci-après appelé PEKK), et un PEKK préparé selon ce procédé et, spécifiquement, un procédé de préparation d'une composition de résine de mélange de PEKK, qui contient un composé à base de phosphite de façon à présenter une stabilité thermique améliorée, et, simultanément, comprend de l'oxyde de diphényle et du 1,4-diphénylbenzène, qui sont ajoutés en tant que monomères de réaction, de manière à améliorer la vitesse de cristallisation pendant une réaction de polymérisation et à améliorer l'aptitude au moulage par injection; et un PEKK préparé par ce procédé. Selon la présente invention, l'invention concerne un procédé de préparation d'une composition de résine de mélange de PEKK, comprenant les étapes consistant à : (A) mettre en place au moins un élément, choisi parmi le 1,4-diphénoxybenzène et le 1,4-bis (4-phénoxybenzoyl)benzène (EKKE), du chlorure de téréphtaloyle (TPC) et du chlorure d'isophtaloyle (IPC), dans un milieu de réaction liquide dans un réacteur et, simultanément, à dissoudre celui-ci, ce qui permet de préparer une solution de réaction; (b) abaisser la température de la solution de réaction, puis injecter un catalyseur; (c) injecter le catalyseur, puis souffler directement un gaz inerte dans la solution de réaction et l'agiter de manière à préparer une résine pure de PEKK; et (d) injecter un composé à base de phosphite dans la résine pure et le mélanger au moyen d'un mélangeur. Par conséquent, la stabilité thermique Est améliorée pendant le traitement de PEKK et, simultanément, l'aptitude au moulage par injection est améliorée par l'amélioration de la vitesse de cristallisation pendant la réaction de polymérisation.
