Document Type and Number:
WIPO Patent Application WO/2021/109621
Kind Code:
A1
Abstract:
A polyamide reverse osmosis membrane and a production method therefor. The polyamide contains a structural unit derived from a sulfonated phenylenediamine monomer, and a structural unit derived from an acyl chloride monomer, and an optional structural unit derived from a non-sulfonated phenylenediamine monomer, wherein, when calculated on the basis of the total weight of the sulfonated phenylenediamine monomer and the non-sulfonated phenylenediamine monomer, the sulfonated phenylenediamine monomer content is from 10% to 100%.
