Atrazine-sensitive conductimetric sensors were designed using molecularly imprinted polymer membranes. Membranes containing artificial recognition sites for atrazine prepared by copolymerization of methacrylic acid and a cross-linker, tri(ethylene glycol) dimethacrylate, in the presence as template. In order to improve flexibility mechanical stability membranes, oligourethane acrylate was added mixture monomers. The complementary formed membranes after extraction template molecules with...
Molecularly imprinted polymer membranes for a model compound, atrazine, were prepared in situ from monomer mixture containing methacrylic acid, tri(ethylene glycol) dimethacrylate, and atrazine using UV-initiated polymerization. To improve flexibility mechanical stability of these membranes, oligourethane acrylate was added to the monomers. Polymeric additives used increase porosity their permeability as well make them suited filtration experiments. This process resulted formation thin,...

Abstract Interpenetrating polymer networks (IPN) of polyurethane and acrylate were obtained. A small‐angle x‐ray scattering technique was used to study the character microheterogeneities in IPN their variation with composition. It shown that formation is accompanied by phase separation constituent components. On basis experimental data, which involved mean square fluctuations electron densities IPN, intensity extrapolated zero angle, thickness transition layer between two phases, degrees...

Segmental relaxations in a series of poly(propylene oxide)-based polyurethane/butyl methacrylate-triethylene glycol dimethacrylate copolymer interpenetrating networks (IPNs) various compositions, as compared to those the pure constituent networks, were studied by an original laser-interferometric Creep Rate Spectroscopy (CRS) technique. The spectra, obtained over range from 150 K 360 K, confirmed CRS superiority resolution generally utilized relaxation spectrometry techniques and allowed...
Abstract The thermodynamic miscibility and thermal dynamic mechanical behaviour of semi‐interpenetrating polymer networks (semi‐IPNs) crosslinked polyurethane (PU) linear poly(hydroxyethyl methacrylate) (PHEMA) have been investigated. free energies mixing the semi‐IPN components determined by vapour sorption method it was established that parameters are positive depend on amount PHEMA in samples. Thermal analyses glass transition temperatures evidenced two semi‐IPNs accordance with...
Gradient semi-interpenetrating polymer networks (gradient semi-IPNs) were synthesized using polyurethane (PU) and poly(vinyl pyrrolidone) (PVP). The materials characterized with respect to thermodynamic miscibility, IR-spectroscopy, mechanical properties morphological structure. positive values of Gibbs free energy indicated that the polymeric systems thermodynamically immiscible. gradient semi-IPNs shown have unique dependent on composition subsequent degree microphase separation. Given...
