      The synthesis and characterization of a new ruthenium(ii) complex containing a hemilabile P^N-ligand are reported. The catalytic activity of this complex was evaluated in the hydrogen transfer reaction of acetophenone and ...
    • Design of highly polarized achiral mesogenic composites 
      Soto Bustamante, Eduardo; Vergara Toloza, Rafael Orlando; Haase, Wolfgang (2012)
      The synthesis of one homologous series of methacrylate monomers and their polymers was carried out to observe the dependence between the polarization and some structural aliphatic features. Investigations of the thermoanalytical, ...
    • Effect of stirring on photoinitiated polymerization 
      Zanocco Loyola, Antonio; Garrido, J.; Lissi Gervaso, Eduardo A. (1988)
      The polymerization of methyl methacrylate photosensitized by benzion methyl ether over a wide range of initiator absorbances was investigated. Both the polymerization rate and the polymer molecular weight distribution are ...
    • Functionalization of polypropylene by grafting with itaconic acid 
      Yazdani-Pedram Zobeiri, Mehrdad; Vega, Héctor; Quijada Abarca, Juan (Wiley-VCH Verlag, 1996)
      Grafting of polypropylene was carried out in both boiling xylene and decalin as solvent medium with itaconic acid (2-methylenesuccinic acid) as functional polar monomer using 2,5-dimethyl-2,5-bis(tert-butylperoxy)hexane ...
    • On the new low-dimensional organic-inorganic hybrid solids Cu 4(bipy)4[V4P2O19] ·nH2O (n ∼ 5) and Cu2(bipy)2[V ... 
      Ushak, S.; Spodine Spiridonova, Evgenia; Venegas Yazigi, Diego; Le Fur, E.; Pivan, J. Y.; Peña, O.; Cardoso-Gil, R.; Kniep, R. (Royal Society of Chemistry, 2005)
      The new hybrid organic-inorganic copper oxovanadium phosphates of composition Cu4(bipy)4V4O11(PO 4)2·nH2O (n ∼ 5) (1) and Cu 2(bipy)2V2P2O12 (2) (bipy = 2, 2′-bipyridine) adopting the triclinic symmetry were obtained by ...
    • Poly(acrylonitrile)-molybdenum disulfide polymer electrolyte nanocomposite 
      Santa Ana, María Angélica; Benavente Espinosa, Eglantina; Gómez Romero, Pedro; González Moraga, Guillermo (2006)
      The synthesis, characterization and electrochemistry of a novel nanocomposite based on the co-intercalation of lithium and poly(acrylonitrile) (PAN) in molybdenum disulfide [Li0.6MoS2(PAN) 1.2·0.5H2O] is described. The ...
    • Polypyrrole molecularly imprinted modified glassy carbon electrode for the recognition of gallic acid 
      Jara Ulloa, Paola Andrea; Salgado Figueroa, Paola; Moscoso Cabello, Raúl Andrés; Squella Serrano, Juan (2013)
      A molecularly imprinted polypyrrole polymer-based film and its properties regarding the recognition of gallic acid were investigated. The polypyrrole film was prepared by including a template molecule during the ...
    • Preparation of new cationic complexes [(η5-C5H5)Fe(dppe)L]PF6 with sulphur and other donor ligands
