摘　　要：设计了一个新的以磺酸阳离子交换树脂为原料制备含硫水不溶性杀菌剂的合成路线。通过聚苯乙烯磺酸吡啶盐中间体合成磺酰氯树脂 ,在磺酰氯树脂上固载二乙胺 ,再用带有叔胺基的树脂与卤代烷作用合成含硫的季铵盐型聚合物杀菌剂。使用所研制的水不溶性杀菌剂用量 2 mg/m L时杀菌率达到 90 %以上。A novel design of preparation route has been set up, in which insoluble bactericides containing sulfur can be synthesized using strongly acidic cation exchange resins as carriers. Firstly, it was needed to synthesize polymeric pyridinium sulfonate and polystyrylsulfonyl chloride resin. After that diethyl amines were carried. Finally, polymeric quaternary ammonium salt bactericides containing sulfur were synthesized by quaternizing the resin containing amine groups with halohydrocarbons. The bactericidal rates of the researched products are more than 90% by the test method of nutrient agar plate to heterotroph.\;
