“…Metal-containing polymers with ionic links formed between COO Ϫ and M 2ϩ have been studied. [11][12][13][14][15][16][17] When polymers are exposed to the atmosphere or are used as adhesive coatings and in biomedicine, they are contaminated or infected by microorganisms such as bacteria. Microorganisms have been found to be the cause of the unbonding and blistering of protective coatings in various service situations.…”

Metal salts of mono(hydroxypentyl)phthalate [M(HPP) 2 , where M is Ca 2ϩ , Cd 2ϩ , Pb 2ϩ , or Zn 2ϩ ] were synthesized by the reaction of 1,5-pentane diol, phthalic anhydride, and metal acetate. A new series of metal-containing polyurethanes containing ionic links in the main chain were synthesized by the reaction of hexamethylene diisocyanate or toluylene 2,4-diisocyanate with the M(HPP) 2 salts. The structures of the monomers and polymers were confirmed with infrared, 1 H-NMR, and 13 C-NMR spectra and elemental analysis. The polymers were also characterized with thermogravimetric analysis, differential scanning calorimetry, and solubility and viscosity measurements. The antibacterial activity of these polyurethanes was investigated with the agar diffusion method.

“…The functionalisation is subsequently carried out by placing the housing inside a thermostat at 65°C and circulating 25 mL of a solution 1 mol/L in sodium sulphite and 0.2 mol/L in tetra‐ n ‐butylammonium hydrogensulphate for 4 h at a flow rate of 0.5 mL/min 7. The monolith is then cleaned by flushing it with 30 mL of water at a flow rate of 0.5 mL/min at room temperature.…”

Polymeric monolithic stationary phases for HPLC can be produced by Reactive Gelation. Unlike the conventional method of using porogens, such novel process consists of a number of separate steps, thus enabling a better control of the quality of the final material. A suspension of polymer nanoparticles in water is produced and subsequently swollen with hydrophobic monomers. The particles are then destabilised (usually by salt addition) to make them aggregate into a large percolating structure, the so-called monolith. Finally, the added monomer can then be polymerised to harden the structure. In this work, a polystyrene latex is used as the base material and functionalised by introduction of epoxide groups on the surface and subsequent reaction to sulphonic acid groups, yielding a SO3(-) density of 0.7 mmol/g dry material. Morphological investigations show 54% porosity made of 300 nm large pores. Van Deemter measurements of a large protein show no practical influence of diffusion limitations on the plate number. Finally, a preliminary separation of a test protein mixture is shown, demonstrating the potential of using ion-exchange chromatography on Reactive Gelation monoliths.

[7][8][9][10][11][12][13][14][15][16] Recently, we proposed a new monomer, 3-chloro-2-hydroxypropyl methacrylate (HPMA-Cl) for the preparation of reactive capillary monoliths for different chromatographic applications. In our recent studies, a new reactive monolith, poly(3-chloro-2-hydroxypropyl methacrylate-co-ethylene dimethacrylate), (poly[HPMA-Cl-co-EDMA]) was synthesized.…”

A new reactive monolith, poly(3‐chloro‐2‐hydroxypropyl methacrylate‐co‐ethylene dimethacrylate), poly(HPMA‐Cl‐co‐EDMA) was synthesized and post‐functionalized by taurine (2‐aminoethane sulfonic acid) to obtain a zwitterionic stationary phase for capillary electrochromatography. The new stationary phase contained charged groups such as secondary amine providing anodic electroosmotic flow and sulfonic acid groups providing cathodic electroosmotic flow. Hence, the capillary electrochromatography separations with the new zwitterionic monolith were performed with either anodic or cathodic electroosmotic flow. The electrochromatographic separation of alkylbenzenes and phenols was successfully performed. The zwitterionic monolith also allowed the separation of nucleosides using only electrokinetic mode. Theoretical plate numbers up to ~105 plates/m were achieved. Our study is the first report based on poly(HPMA‐Cl‐co‐EDMA) reactive monolith post‐functionalized with a zwitterionic ligand allowing to operate in both anodic and cathodic electroosmotic flow modes.
