In this research acrylate – styrene copolymer containing quaternary nitrogen atoms was synthesized by a bulk copolymerization method according to free radical mechanism. Antibacterial activity of this resin was examined by changing parameter values such as: types and amount of the neutralized agents, temperature of the neutralization reaction, etc. The antibacterial properties of the acrylate – styrene copolymer were evaluated via the agar diffusion test. In addition, the molecular structure of the copolymer was performed in Fourier transformation infrared (FTIR) spectroscopy. Besides that, the hydrogels from the acrylate – styrene copolymer were also examined on their antibacterial properties. As results, the copolymer showed the highest antibacterial activities with the ratio of ammonia to acrylic acid about 0.8:1 and the neutralizing temperatures at 60 °C.
