内容記述 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 < 1000 Da. However, only colloids prepared using a cationic initiator VA-044 or V-50 and capable of forming stable dispersions were antimicrobially active. Colloids synthesized using an anionic initiator KPS or V-501, which aggregate easily due to electro-attractive forces between functional groups, were not antimicrobial. Thus, the antimicrobial activity of a polymer colloid is closely associated with its ability to form a stable dispersion.
