COMPOSITE SEMIPERMEABLE MEMBRANE AND METHOD FOR PRODUCING SAME

Document Type and Number:

WIPO Patent Application WO/2017/002699

Kind Code:

A1

Abstract:

The purpose of the present invention is to provide: a composite semipermeable membrane, the water permeation performance of which is not susceptible to change even if the composite semipermeable membrane is cleaned with a strong alkaline solution; and a method for producing this composite semipermeable membrane. A composite semipermeable membrane according to the present invention is obtained by forming a skin layer containing a polyamide resin on the surface of a porous supporting body; and the polyamide resin contains a carbodiimide compound as a staring material component.
