PREDICTION OF MONOMER REACTIVITY RATIOS IN RADICAL COPOLYMERIZATION OF VINYL MONOMERS
Sep 01, 2009; ... Quantitative structure-property relationship (QSPR) models are developed to predict monomer reactivity ratios (log r^sub 12^) in radical copolymerization with monomers M^sub 1^ (styrene, methyl methacrylate and acrylonitrile) and M^sub 2^ (vinyl monomers). The quantum chemical descriptors are ...
SYNTHESIS AND SPECTROSCOPIC INVESTIGATION OF (ACETYLAMINO)PYRIDINES
Sep 01, 2009; ... The self-association of 2- and 3-(acetylamino)pyridines in a condensed phase was investigated by conventional and linear-polarized IR spectroscopy. Interpretation of spectra of the monomer and associated forms was carried out by the reducing-difference procedure. Theoretical quantum chemical ...
ADSORPTION OF TETRAMETHYLTHIOUREA IN CONCENTRATED NaClO^sub 4^ SOLUTIONS
Sep 01, 2009; ... Tetramethylthiourea electrosorption behaviour on the mercury electrode in 2, 3 and 4 mol I^sup -1^ NaClO^sub 4^ was determined by means of double-layer differential capacity measurements. The relative surface excess Γ' of the adsorbate calculated from the surface pressures depended on the ...
DIFFUSION EXPERIMENTS AS A NEW APPROACH TO THE EVALUATION OF COPPER TRANSPORT IN HUMICS-CONTAINING SYSTEMS
Sep 01, 2009; ... Diffusion measurements seem to provide a valuable approach to mapping studies on heavy metal transport in systems containing humic substances. The paper deals with the diffusion of cupric ions in a humic hydrogel. The diffusion coefficients of Cu^sup 2+^ in this medium were determined using ...
REGIO- AND STEREOSELECTIVITY OF [2+3]CYCLOADDITION OF NITROETHENE TO (Z)-N-ARYL-C-PHENYLNITRONES+
Sep 01, 2009; ... The cycloaddition reactions of nitroethene to (Z)-N-aryl-C-phenylnitrones lead to mixtures of stereoisomeric cis- and trans-2-aryl-4-nitro-3-phenylisoxazolidines. Regioselectivity of these reactions is determined by the character of nucleophile-electrophile interactions, while stereoselectivity ...
