The bactericidal monomer 2,4,4′‐trichloro‐2′‐acrylolyoxydiphenyl ether (AcDP) was synthesized from 2,4,4′‐trichloro‐2′‐hydroxydiphenyl ether (DP) and acryoyl chloride in the presence of triethylamine in dry THF at 20°C. The synthesized AcDP was indentified by IR, 1 H‐NMR, and GC‐MS spectra. The homopolymer of AcDP was obtained using BPO an an initiator in toluene at 70°C. Copolymer of AcDP and styrene (St) was synthesized with a free radical initiator at 70°C. Poly(AcDP) and poly(AcDP‐co‐St) were identified by IR and 1 H‐NMR spectra. The maximum weight average molecualr weight ( Mw ) of poly(AcDP) and poly(AcDP‐co‐St)s were 4100 and 11600, respectively. The monomer reactivity ratios, r 1 (AcDP) and r 2 (St), determined by the Kelen–Tüdös method, were 0.16 and 0.33, respectively. The glass transition temperature and decomposition temperature of poly(AcDP) were 73.4°C and 348°C, respectively. The bactericidal activities of AcDP, poly(AcDP), and poly(AcDP‐co‐St) were studied using agar dish test. The bactericidal activities of AcDP and its polymers as well as DP agianst Pseudomonas Aeruginosa were very excellent compared to those of control polymers such as poly(St) and poly(ethylene‐co‐vinyl acetate). The bactericidal activities were decreased in the order DP > AcDP > poly(AcDP) > poly(AcDP‐co‐St) Against Pseudomonas Aeruginosa . © 1994 John Wiley & Sons. Inc.
