摘要(Abstract)：
用对氯甲基苯乙烯和三丁基膦合成对乙烯基苄基三丁基氯化鏻(简称三丁基季鏻盐),对其结构进行表征,并研究了其热稳定性和抗菌活性。结果表明三丁基季鏻盐具有良好的热稳定性;MIC(最低杀菌浓度)法测定结果表明,三丁基季鏻盐对大肠杆菌(E.coli)的MIC为0.4g/L,对金黄色葡萄球菌(S.aureus)的MIC为0.3g/L;用熔融挤出法制备三丁基季鏻盐接枝低密度聚乙烯类抗菌塑料,当三丁基季鏻盐的质量分数达到2.13%时对E.coli的杀菌率达到96.0%,对S.aureus的杀菌率达到99.0%以上,当三丁基季鏻盐质量分数达到3.20%时对2种细菌的杀菌率都达到99.9%以上。
