A water-insoluble liquid crystalline gel composed mainly of a water-soluble polymer, itself having a gelation function together with a liquid crystal formation function and having an optical property is produced. First, the water-soluble polymer is dissolved in water or an aqueous solution containing a salt(s) to prepare a polymer solution. Subsequently, this polymer solution is dialyzed in an aqueous solution containing a chemical crosslinking agent, thereby obtaining the gel having a liquid crystal structure and composed mainly of the water-soluble polymer. Said water soluble polymer is one or two or more polymers selected from the group consisting of water-soluble biopolymers, derivatives of these water-soluble biopolymers and water-soluble synthesized polymers. The water-soluble biopolymers are one or two or more polymers selected from the group consisting of nucleic acids, polysaccharides, proteins, modified proteins and polyamino acids. The water-soluble synthesized polymers are one or two or more polymers selected from the group consisting of polyvinyl alcohol, polyethylene glycol, polyacrylic acid and polystyrene sulfonic acid. |
