Abstract:
(EN) The present invention pertains to a semipermeable composite membrane having a support film and a separation function layer, wherein, (A) in a semipermeable composite membrane equilibrated under specific conditions, the half value width H of an absorption peak between 3900 cm-1 and 2900 cm-1 in a difference spectrum Sd obtained by subtracting IR spectrum S2 from IR spectrum S1 is 355-373, and (B) in the IR spectrum S1, the value F obtained by dividing the area of the absorption intensity between 3900 cm-1 and 2900 cm-1 by the absorbance at the peak top between 1690 cm-1 and 1630 cm-1 is at least 850.
(FR) La présente invention concerne une membrane composite semi-perméable comportant un film de support et une couche fonctionnelle de séparation. Selon l'invention : (A) dans une membrane composite semi-perméable équilibrée sous des conditions spécifiques, la largeur de demi-valeur H d'un pic d'absorption entre 3900 cm-1 et 2900 cm-1, dans un spectre de différence Sd obtenu en soustrayant le spectre IR S2 du spectre IR S1, est comprise entre 355 et 373, et (B) dans le spectre IR S1, la valeur F obtenue en divisant l'aire de l'intensité d'absorption entre 3900 cm-1 et 2900 cm-1 par l'absorbance au sommet de pointe entre 1690 cm-1 et 1630 cm-1 est d'au moins 850.
(JA) 本発明は、支持膜と分離機能層とを備え、(A)特定条件で平衡化された複合半透膜における、IRスペクトルS1からIRスペクトルS2を減じた差スペクトルSdにおいて、3900cm-1から2900cm-1間の吸収ピークの半値幅Hが355以上373以下であり、(B)前記IRスペクトルS1において、3900cm-1から2900cm-1間の吸収強度の面積を、1690cm-1から1630cm-1間のピークトップの吸光度で割った値Fが850以上である、複合半透膜に関する。
