A method of producing a DN gel membrane includes a step (1) including producing a 1st gel membrane by (i) casting, on a substrate, a solution containing an ionic liquid A and an ionic liquid B, the ionic liquid A being made up of 1st monomers each of which has a polymerizable functional group and (ii) polymerizing the 1st monomers; and a step (2) including producing the DN gel membrane by (i) immersing the 1st gel membrane in a solution containing 2nd monomers which are different from the 1st monomers and (ii) polymerizing the 2nd monomers. This method allows for continuous-type production which is suitable for industrial mass production of DN gel membranes or acid gas separation membranes.

A method for preparing comb structure temperature/pH-responsive polycarboxylic acid by end-group functionalization adopts temperature/pH-responsive monomer, unsaturated halogenated hydrocarbon, small monomer of carboxylic acid and other raw materials to prepare polycarboxylic acid material via self-polymerization, substitution and copolymerization. Temperature/pH-responsive monomers are first self-polymerized to obtain temperature/pH-responsive polymer chain with end-group functionalization, and then substitution with unsaturated halogenated hydrocarbons is conducted to obtain temperature/pH-responsive macromonomers with end-group functionalization, finally the obtained product is copolymerized with small carboxylic acid monomers to prepare comb structure polymer with polycarboxylic acid main chain and temperature/pH-responsive side chain.
