Title (EN) SEMIPERMEABLE MEMBRANE
(FR) MEMBRANE SEMI-PERMÉABLE
(JA) 半透膜
Abstract:
(EN) Provided is a semipermeable membrane having high chlorine resistance. The semipermeable membrane comprises cellulose ester, and the cellulose ester has a benzoyl group which may have a substituent.
(FR) L’invention fournit une membrane semi-perméable présentant une résistance au chlore élevée. Plus précisément, l’invention concerne une membrane semi-perméable qui est constituée d’un ester de cellulose. Ledit ester de cellulose possède un groupe benzoyle éventuellement substitué.
(JA) 耐塩素性の高い半透膜の提供。 セルロースエステルからなる半透膜であって、前記セルロースエステルが、置換基を有していてもよいベンゾイル基を有しているものである、半透膜。
