Resumen de: CN121079346A

An anion exchange membrane, particularly suitable for use in electrolytic cells and fuel cells, includes a polyolefin support and an active copolymer containing monomeric units derived from an acrylic monomer having a long saturated linear alkyl chain. A saturated linear alkyl chain of a monomer unit derived from an acrylic monomer having a sufficient length of the active copolymer interacts with a similar saturated linear chain exposed on the surface of a polyolefin support, resulting in: adhesion of the active copolymer on the support, thereby allowing an anion exchange membrane having high mechanical properties and durability to be obtained; the positive charge of the active copolymer is isolated within the pores of the polyolefin support, promoting the formation of positively charged ion channels, thereby promoting the migration of hydroxide ions and allowing high performance of electrochemical cells to be achieved. The anion exchange membrane according to the invention can be obtained in an economically advantageous manner by a special process comprising promoting polymerization of a monomer mixture in a reactor, activating the copolymer by piperidine tertiary amine and/or pyrrolidine tertiary amine, promoting formation of quaternary ammonium salts and promoting adhesion of the copolymer to a polyolefin support.
