A new original application for a polyacrylic film based on the monomers 2-(dimethylamino)ethyl methacrylate (NNDA), 2-hydroxyethyl acrylate (2HEA) and methylmethacrylate (MMA) as starch azure container has been set up simple determination of honey diastase activity. The proposed method is correlation reducing sugars generated during enzymatic process with Schade reference assay. charged acting ...

The detailed structural characterization of complex polymer architectures, like copolymers and polymer mixtures, by mass spectrometry presents a challenge. Even though soft ionization analyses revolutionized the characterization of large molecules and provided a means for determining the polymer's molecular weight distribution, polydispersity, and end groups, full microstructure elucidation and...

Polymerization supported by a high dc voltage results in charged macromolecules with conductivity, reduced molecular weight, and moderate dispersity.

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2013200520 DESCRIPTION Derivatives of methacrylic acid showing strong sensitising properties are frequent causes of allergic contact dermatitis in dentists and dental technicians. Methyl methacrylate is used for fabrication of acrylic removable partial or complete ...

in order to increase the water content and the oxygen permeability of hydrogels used in themanufacture of contact lenses, the polar monomer silicon hydrogel contact lenses (shcl), and 2-hydroxyethyl methacrylate (hema) were copolymerized with the hydrogels. due to the presence ofpolar monomers in the conventional contact lenses, the major component of the human tear,lysozyme is extensively adso...

The inverse gas chromatography, (IGC), method has been used extensively to study the structure of polymers, the interactions of various liquids and gases with polymeric materials, and polymer-polymer miscibility. The method is simple, fast and economical and provides valuable thermodynamic information for characterization of polymeric materials1−6. In this study, we examined the interactions of...

Hydrogels are widely used in the biomedical field. Their main purposes are either to deliver biological active agents or to temporarily fill a defect until they degrade and are followed by new host tissue formation. However, for this latter application, biodegradable hydrogels are usually not capable to sustain any significant load. The development of biodegradable hydrogels presenting load-bea...

The polymerization by radiofrquency (RF) plasma of different monomers (methyl methacrylate (MMA), tetraglyme and 2-hydroxyethyl methacrylate (HEMA)) has been carried out. The plasma gas was investigated by optical emission spectroscopy (OES) in the UV-vis wavelength rang. The excited species formed in the plasma were identified for the different monomers. From computer simulations of the ro-vib...
