Antibacterial and Bacterium Adsorbing Macromolecules

Abstract

Currently studies on antibacterial macromolecules, i. e., bactericidal and bacteriostatic ones, have been made to develop a new utilization field of polymeric materials. In these studies, there are immobilizations of iodine to quaternary ammonium salts, antibiotics, antibacterial groups to macromolecular substances, as well as syntheses of polymers with quaternary ammonium salts, biguanide groups, quaternary pyridinium salts, sulphonium salts, phosphonium salts, and other antibacterial groups. On the other hand, studies have been made of bacterium adsorbing macromolecules, which can remove by adsorbing bacterial cells in water. The macromolecules are the ones based on poly(4-vinylpyridine-co-divinylbenzene), crosslinked poly(3- and 4-chloromethylated styrene-g-amine), and poly(glycidyl methacrylate-g-amine), as well as filters and microporous membranes are covered with a macromolecule based on quaternized poly(4-vinylpyridine-co-styrene). Here, a review is made of the syntheses and preparation of the respective macromolecules, as well as of their antibacterial activities and the bacterium adsorbing activities.
