比较了N-氯化聚合物微球和两种聚季铵盐微球的生物杀灭效果。在金黄色葡萄球菌或大肠杆菌的水性悬浮液与水不溶性珠短暂接触后测量杀生物效果。聚合物主链在所有三种类型的珠中保持相同，因此它们仅在其杀生物衍生物部分中不同。在所有情况下，进行交联的氯甲基化聚苯乙烯珠的官能化以引入杀生物性质。将介绍合成方法和测试数据。最有效的杀生物剂，作为衡量在最短的接触时间的两种细菌的失活程度，是N-氯化乙内酰脲衍生物的甲基化聚苯乙烯。(C)2004 Wiley Periodicals，Inc. J Appl Polym Sci 92：363-367，2004.
A comparison has been made between the biocidal efficacies of N-chlorinated polymeric beads and two derivatives of polyquat beads. Biocidal effects were measured after brief contact exposures of aqueous suspensions of either Staphylococcus aureus or Escherichia coli to the water-insoluble beads. The polymeric backbone was held the same in all three types of beads, so they differed only in their biocidal derivative moieties. In all cases, functionalization of crosslinked chloromethylated polystyrene beads was performed to introduce the biocidal properties. Synthetic methods and test data will be presented. The most effective biocide, as measured by degree of inactivation in the shortest contact time of the two species of bacteria, was the N-chlorinated hydantoinyl derivative of methylated polystyrene.
