The chloromethylated crosslinked polystyrene with chlorine content of 3.9, 3.7 and 2.7 mmol/g were prepared by chloromethylating crosslinked polystyrene with crosslinkage of 2%, 4% and 5% respectively. The insoluble quaternary ammonium bactericides with quaternary ammonium content of 2.6, 2.5 and 2.2 mmol/g quaterisated resin were prepared by treating the chloromethylated polystyrene with dimethyldodecyl ammonium. It is found that the more crosslinkages in chloromethylated polystyrene, the smaller the pore volume, the less the chlorine content, then the less the ammonium amount in resin and the less antibactericidal activity of the polymer bactericides.
- insoluble bactericide,
- chloromethylated crosslinked polystyrene,
