11-(4,4-Dimethyl-2,5-dioxoimidazolidin-1-yl)undecyl acrylate was synthesized in a two-step procedure using microwave irradiation. Poly(acrylates) containing fluorinated and hydantoin (5,5-dimethylimidazolidine-2,4-dione) moieties were prepared by free radical polymerization of 2-(perfluorooctyl)ethyl acrylate and the synthesized monomer with the aim of obtaining low surface energy polymeric materials with properties of contact-active biocides. Polymeric films were treated with a bleaching solution in order to convert the hydantoin units to N-halamines, well-known contact-active biocides. The reversibility of the chlorination reaction, necessary to impart a renewable biocide effect, was investigated by Fourier Transform-Attenuated Total Reflection. Preliminary biological tests conducted against Bacillus megaterium demonstrated the effective biocide properties of the prepared materials.

AbstractIron shows fast heat development under microwave (MW) irradiation. This property was used to start polymerization reactions on the surface of iron fibres. MW irradiation of metal fibres, which are located in a monomer solution consisting of methyl methacrylate, ethylene glycol dimethacrylate, N,N’-azoisobutyronitrile and toluene led to the formation of polymer on the metal fibre surface. After dissolving the covered iron component in hydrochloric acid, a channelcontaining polymeric material was obtained. Scanning electron microscopy showed a smooth material with rough inner channels. These internal surface structures were caused by the rough surface of the metal fibres.

Aim and Objective: Microwave-assisted condensation of acetophenone 1 and aromatic aldehydes 2 gave chalcone analogs 3, which were cyclized to pyrazole derivatives 6a-f via the reaction with hydrazine hydrate and oxalic acid in the presence of the catalytic amount of acetic acid in ethanol. Materials and Methods: The structural features of the synthesized compounds were characterized by melting point, FT-IR, 1H, 13C NMR and elemental analysis. Results: The antibacterial activities of the synthesized pyrazoles was evaluated against three gram-positive bacteria such as Enterococcus durans, Staphylococcus aureus, Bacillus subtilis and two gram-negative bacteria such as Escherichia coli and Salmonella typhimurium. Conclusion: All the synthesized pyrazoles showed relatively high antibacterial activity against S. aureus strain and none of them demonstrated antibacterial activity against E. coli.
