Abstract Cationic polymers synthesized from aromatic monomers such as styrene or 4-vinylaniline, and with molecular weight less than 1000 Da display antibacterial activities against Micrococcus luteus. We prepared polymer colloids exhibiting different tendencies to form stable dispersions in order to clarify the influence of this property on their antimicrobial activity against M. luteus. 4-Vinylaniline was polymerized by a soap-free emulsion procedure using cationic and anionic initiators to prepare polymer colloids with different capacities for forming dispersions. All synthesized colloids displayed positive zeta potentials due to the presence of amino groups from the monomers and/or initiators and included polymers with molecular weights

聚（4-乙烯基苯胺）胶体的分散形成能力与抗菌活性的关系

摘要 由苯乙烯或4-乙烯基苯胺等芳香族单体合成的分子量小于1000 Da的阳离子聚合物对藤黄微球菌具有抗菌活性。我们制备了表现出不同倾向的聚合物胶体以形成稳定的分散体，以阐明这种特性对其对藤黄葡萄球菌的抗菌活性的影响。4-乙烯基苯胺通过使用阳离子和阴离子引发剂的无皂乳液聚合制备具有不同形成分散体能力的聚合物胶体。由于单体和/或引发剂中存在氨基，所有合成的胶体都显示出正 zeta 电位，并且包括具有分子量的聚合物
