“…The chlorination of polyacrylamide grafted onto cotton has been described and investigated. 18,19 Because of the poor chlorine content of the ADMH/PEGDA sample, the influence of the molar ratio and the total monomer concentration was determined with the ADMH/ MBAA formulation. The following experiments were carried out under the same conditions as described in the Experimental section (Table I, MBAA dip).…”

An advanced method with an initiator pretreatment was developed for the coating of nylon/cotton fabrics with the hydantoin-containing monomer 3-allyl-5,5-dimethylhydantoin and two water-soluble crosslinkers N,N 0 -methylene bisacrylamide and poly(ethylene glycol) 200 diacrylate. The formulations were applied to textiles by either batch coating or dip coating. In the dip-coating process, the influence of individual parameters on the fabric modification was investigated and evaluated. After treatment with chlorine, the hydantoin structure was transformed into antimicrobial active N-halamines. The modified fabrics exhibited potent antibacterial properties against Staphylococcus aureus and Escherichia coli. Our method, based on an initiator pretreatment and watersoluble crosslinkers, outperformed current technologies in the degree of fabric modification.

“…The difference in response may have occurred because the viscosity of the reaction system increased with monomer content. It was unfavorable for the polymer radicals to contact with (1). Meanwhile, the concentration of polymer free radicals and initiator radicals in the system increased, which enhanced the termination rate of large molecular free radicals.…”

“…However, the acceleration of the decomposition rate of KPS produced more free radicals in the reaction system. This meant that more free radicals were simultaneously contending for (1). At the same time, the rise in temperature also increased the chance of coupling termination and disproportionation termination of the polymerization, which consequently might have induced the decrease in MW.…”

“…22,23 As the polymers have higher local charge density than the corresponding monomer, the process (1) is expected to have a large driving force. 22,25 This might be the reason that (2) exhibited better antibacterial activity than (1).…”

“…The polymers might still retain good antibacterial activity if being immobilized on material surfaces, as the good water solubility allows them to stretch and contact bacteria cells freely. Therefore, it might be beneficial to use (1) in the antibacterial modification of material surfaces, so as to respond to the increasing need for the development of antibacterial materials.…”

An antibacterial quaternary ammonium acrylic monomer (1) was synthesized by quaternization of 2-dimethylamino ethyl methacrylate with dimethyl sulfate. This synthetic route to quaternary ammonium salt monomer proved to be of high yield and lower cost than that used to synthesize alkyl halide. The corresponding homopolymers (2) were then obtained by free radical polymerization using potassium persulfate as the initiator. The chemical structure was characterized by Fourier transform infrared and 1 H-nuclear magnetic resonance, and molecular weights (MWs) were compared by the viscosity method. Factors influencing the synthesis of (1) and (2) were also investigated. Antibacterial activity was tested against Escherichia coli and Staphylococcus aureus using a minimum biocidal concentration test and the shaking flask method. Monomer (1) exhibited moderate antibacterial activity; however, the polymers had significantly stronger antibacterial activity than the monomer. Therefore, their potential for antibacterial application was established. Similar to other quaternary ammonium compounds, the antibacterial activity of the polymers depended on their MW, and this dependence varied with the type of testing microorganisms.
