摘要：

A series of polystyrene-supported polyethylene glycols (PS-PEG), as a new kind of water insoluble antibacterial resins, were obtained through graft-polymerization between chloromethylated polystyrene (CMPS) and PEG. The resins after adsorbing iodine showed excellent antibiotic activities on Escherichia coli and Staphylococcus aureus by adopting plate counting method. The antibiotic abilities were directly influenced by iodine adsorption capacity and the molecular weight of PEG. The resins under the wet state show more efficiency than those under dry state. Among these resins, PS-4-PEG800 has the strongest bactericidal ability under the wet state, which could inhibit 99.3% and 93.8% on the E. coli and S. aureus, respectively. Furthermore, it is also a kind of environment-friendly material and can be easily separated from the sterilized water.
