Allyl dimethyl dehydroabietyl ammonium chloride (ADMDHA), as a cationic quaternary ammonium polymerizable antibacterial surfactant, was synthesized from dehydroabietylamine and 3‐chloropropene. The structure of ADMDHA was characterized by FT‐IR, NMR, and elemental analysis. The critical micelle concentration (CMC) of ADMDHA and the surface tension at the CMC (γ CMC ) in aqueous solution were about 2.51 × 10 −4 mol L −1 and 28.5 mN m −1 at 25 °C, respectively. The emulsion consisting of benzene and water with ADMDHA as an emulsifier maintained its stability for 2 days. Meanwhile, the antimicrobial activities of ADMDHA against Escherichia aerogenes and Pseudomonas aeruginosa were much stronger than those of ampicillin sodium and bromogeramine against the same bacteria.
