Title (EN) METHOD FOR MODIFICATION OF LIQUID CRYSTAL POLYMER
(FR) PROCÉDÉ DE MODIFICATION DE POLYMÈRE À CRISTAUX LIQUIDES
(JA) 液晶ポリマーの改質方法
Abstract: front page image
(EN)Disclosed is a method for modification of a liquid crystal polymer. The method comprises the step of irradiating a liquid crystal polymer with a laser beam having a pulse width of 10-12 second or less. The method enables to provide a liquid crystal polymer having improved physical strength compared to a conventional liquid crystal polymer.
(FR)La présente invention concerne un procédé pour la modification d'un polymère à cristaux liquides. Le procédé comprend une étape consistant à irradier un polymère à cristaux liquides avec un faisceau laser dont la largeur d'impulsion est inférieure ou égale à 10-12 secondes. Ce procédé permet d'obtenir un polymère à cristaux liquides dont la résistance physique est améliorée par rapport à un polymère à cristaux liquides conventionnel.
(JA) 液晶ポリマーにパルス幅が10-12秒以下のレーザーを照射する工程を包含する、液晶ポリマーの改質方法。従来の液晶ポリマーと比較して物理的強度を向上させることができる。
