Inventor(s) include Van Rijen Adrianus Jacobus; Hessing Jacko; and Huerta Martinez Elisa.

The application for the patent was published on Aug. 8, under issue no. 32/2025.

According to the abstract released by the Intellectual Property India: "An anion exchange membrane obtainable by curing a curable composition comprising: (a) a monomer (a) of Formula (I) wherein: each n independently has a value of 1 or 2; (i) Ra and Rb are each independently an optionally substituted C1 3 alkyl group or an optionally substituted C2 3 alkenyl group; or (ii) Ra and Rb together with the positively charged nitrogen atom to which they are attached form an optionally substituted 5 or 6 membered ring; or (iii) one of Ra and Rb is an optionally substituted C1 3 alkyl group or an optionally substituted C2 3 alkenyl group and the other of Ra and Rb together with the group of formula AR1 ??? (CH2)n ??? N+ forms an optionally substituted 5 or 6 membered ring; or (iv) Ra together with the group of formula AR1 ??? (CH2)n ??? N+ forms an optionally substituted 5 or 6 membered ring and Rb together with the group of formula N+??? (CH2)n ??? AR2 forms an optionally substituted 5 or 6 membered ring; X is an anion; and AR1 and AR2 each independently comprise aromatic groups; wherein: (I) at least one of AR1 and AR2 comprises a curable ethylenically unsaturated group; (II) the monomer (a) of Formula (I) comprises at least two curable ethylenically unsaturated groups; and (III) the ion exchange capacity (IEC) of the anion exchange membrane is below 1.65 meq/g dry membrane."

The patent application was internationally filed on Sept. 26, 2023, under International application No.PCT/EP2023/076498.
