Abstract
A fibrous polyion complex or a polyion complex shapable to a mass or a film is prepared by reacting polycation having polymerization degree of not less than 5 or polyamine having polymerization degree of not less than 6 with polycarboxylic acid having polymerization degree of not less than 5. At least one of the reactants may preferably be of long chain polymer if fibrous polyion complex is desired.
