CHLORINE RESISTANT DESALINATION MEMBRANES BASED ON DIRECTLY SULFONATED POLY(ARYLENE ETHER SULFONE) COPOLYMERS

摘要

The present invention provides a membrane, kit, and method of making a hydrophilic- hydrophobic random copolymer membrane. The hydrophilic-hydrophobic random copolymer membrane includes a hydrophilic-hydrophobic random copolymer. The hydrophilic-hydrophobic random copolymer includes one or more hydrophilic monomers having a sulfonated polyarylsulfone monomer and a second monomer and one or more hydrophobic monomers having a non-sulfonated third monomer and a fourth monomer. The sulfonated polyarylsulfone monomer introduces a sulfonate into the hydrophilic- hydrophobic random copolymer prior to polymerization.
