Abstract
PURPOSE: To easily prepare a chitosan molded product, by molding an aqueous solution of a chitosan by use of an aqueous solution of an anionic surfactant as a coagulating bath.
CONSTITUTION: A chitosan (salt) is suspended in an aqueous solution of an acid or water and heated at 20W90°C with agitation, to obtain an aqueus solution of the chitosan (salt) (hereinafter referred to as dope). Then the dope is introduced through filtrotion and defoaming to a molding step, where it is molded by being extruded at 20W80°C into a coagulating solution consisting of an aqueous solution of an anionic surfactant (e.g., a polyoxyethylenealkyl sulfate) in an amount corresponding to the amino group equivalent of the chitosan in the dope, or being extruded into air or steam and immersed in the coagulating bath.
USE: An adsorbent, ion exchanger, chelating agent, dialysis membrane, etc.
