Title (EN) PROCESS FOR PRODUCING POLYETHER KETONE KETONE
(FR) PROCESSUS DE PRODUCTION DE POLYÉTHERCÉTONE-CÉTONE
Abstract:
(EN) The invention concerns a method for the manufacture of polyether ketone ketone (PEKK), comprising the step consisting in: (i) Providing a 1,4-bis(4-phenoxybenzoyl)benzene-Lewis acid complex; (ii) Purifying said 1,4-bis(4-phenoxybenzoyl)benzene-Lewis acid complex; (iii) reacting said 1,4-bis(4-phenoxybenzoyl)benzene-Lewis acid complex with at least one difunctional aromatic acyl chloride in a reaction solvent and optional additional Lewis acid to obtain a product mixture comprising a PEKK-Lewis acid complex; and (iv) decomplexing the PEKK-Lewis acid complex to obtain a PEKK polymer. The invention further concerns a composition comprising at least 40 wt.% of 1,4-bis(4- phenoxybenzoyl)benzene - Lewis acid complex and an anhydrous aprotic solvent or solvent mixture, characterized in that it comprises less than 1 wt.%, preferably less than 0.5 wt.% and in particular less than 0.1 wt.% of molecules comprising xanthydrol groups and its use for the manufacture of polyether ketone ketone.
(FR) L'invention concerne un procédé de fabrication de polyéthercétone-cétone (PEKK), comprenant les étapes consistant à : (i) fournir un complexe 1,4-bis(4-phénoxybenzoyl)benzène-acide de Lewis ; (ii) purifier ledit complexe 1,4-bis(4-phénoxybenzoyl)benzène-acide de Lewis ; (iii) faire réagir ledit complexe 1,4-bis(4-phénoxybenzoyl)benzène-acide de Lewis avec au moins un chlorure d'acyle aromatique difonctionnel dans un solvant de réaction et éventuellement un acide de Lewis supplémentaire pour obtenir un mélange de produits comprenant un complexe PEKK-acide de Lewis ; et (iv) décomplexer le complexe PEKK-acide de Lewis pour obtenir un polymère PEKK. L'invention concerne en outre une composition comprenant au moins 40 % en poids de complexe 1,4-bis(4-phénoxybenzoyl)benzène-acide de Lewis et un solvant aprotique anhydre ou un mélange de solvants, et caractérisée en ce qu'elle comprend moins de 1 % en poids, de préférence moins de 0,5 % en poids et en particulier moins de 0,1 % en poids de molécules comprenant des groupes xanthydrol et son utilisation pour la fabrication de polyéthercétone-cétone.
