N-acryloyl-N-phenylthiourea (APTU) is synthesized by reacting acryloyl chloride with phenylthiourea in the presence of triethylamine (TEA) as a base and characterized by FT-IR, 1 H-NMR and mass spectra. The acrylic polymers from different feed ratios of ethylacrylate (EA), methylmethacrylate (MMA), styrene (St) and APTU have been prepared by emulsion polymerization in water containing sodium lauryl sulfate as a surfactant and ammonium persulfate as a water-soluble radical initiator. The polymers are characterized by FT-IR spectroscopy. The solubility is tested in various polar and non-polar solvents. The molecular weight and polydispersity are determined using gel permeation chromatography (GPC). Thermal behavior of the prepared polymers is also investigated by thermogravimetrical analysis (TGA). The polymers are tested for their antimicrobial activities against selected microorganisms.
