Title (EN) METHOD FOR MANUFACTURING LIQUID CRYSTAL POLYESTER MOLDED BODIES
(FR) PROCÉDÉ DE FABRICATION DE CORPS MOULÉ EN POLYESTER CRISTALLIN
(JA) 液晶ポリエステル成形体の製造方法
Abstract: front page image
(EN)The present invention pertains to a method for manufacturing liquid crystal polyester molded bodies, said liquid crystal polyester having repeating units represented by general formulas (1), (2) and (3). The method for manufacturing liquid crystal polyester molded bodies comprises: a step for carrying out melt filtering using a filter after melt extrusion has been carried out on the liquid crystal polyester; and a step for forming the liquid crystal polyester using an injection molding machine after drying the liquid crystal polyester. The filtration precision of the filter is 1 to 50 μm.
(FR)L'invention concerne un procédé de fabrication de corps moulé en polyester cristallin. Ledit polyester cristallin possède des unités répétitives représentées par les formules générales (1), (2) et (3). Ce procédé de fabrication de corps moulé en polyester cristallin comporte : une étape de filtrage de matière fondue à l'aide d'un filtre, après extrusion de matière fondue de polyester cristallin; et une étape de moulage du polyester cristallin à l'aide d'une presse à mouler par injection, après séchage du polyester cristallin. Plus précisément, l'invention concerne un procédé de fabrication de corps moulé en polyester cristallin dans lequel la précision de filtrage dudit filtre est de 1 à 50μm.
(JA) 本発明は、液晶ポリエステル成形体の製造方法であって、前記液晶ポリエステルが、下記一般式(1)、(2)及び(3)で表される繰返し単位を有し、 前記液晶ポリエステル成形体の製造方法が、液晶ポリエステルを溶融押出した 後、フィルタを用いて溶融ろ過する工程、及び、液晶ポリエステルを乾燥後、射 出成形機を用いて液晶ポリエステルを成形する工程を含み、 前記フィルタのろ過精度が1~50μmである、液晶ポリエステル成形体の製造方法に関する。
