Abstract: A polymer which contains amorphous aluminosilicate particles holding metal ions having a bactericidal action is physically stable and enables an ideal antibacterial or bactericidal action by the antibacterial metal ion in an excited state. The polymer is produced by mixing an organic polymer with said amorphous aluminosilicate solid particles before the polymer is molded. alternatively the polymer is, produced by molding an organic polymer containing amorphous aluminosilicate solid particles, and treating the molded organic polymer with a solution of a water-soluble salt of a metal having a bactericidal action, thereby allowing the metal ions to be held on at least some of the …
