    • 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, ...
    • Ferroelectricity in achiral liquid-crystal systems 
      Yablonskii, S. V.; Soto Bustamante, Eduardo; Vergara Toloza, Rafael Orlando; Haase, Wolfgang (WILEY-V C H VERLAG GMBH, 2004-11-04)
      Ferroelectricity can be defected in systems consisting of liquid-crystal line monomer-polymer mixtures possessing no chiral centers The ferroelectric behavior in mixtures of achiral liquid-crystalline side-chain polymers ...
    • Light sensitive antiferroelectric achiral copolymers 
      Soto Bustamante, Eduardo; González Henríquez, Carmen M.; Vergara Toloza, Rafael Orlando; Haase, Wolfgang (ROYAL SOC CHEMISTRY, 2012)
      Five copolymers were prepared by polymerization of azo-benzene methacrylate monomers in solution using AIBN as initiator. The mesophases were observed by a polarizing light microscope which showed tilted smectic C phases ...
    • Phase characterization of LC (meth)acrylic monomers based on omega-hexyloxy- and omega-undecyloxy-salicylaldimine ... 
      Soto Bustamante, Eduardo; González Henríquez, Carmen M.; Rodríguez Lehyt, G. A.; Vergara Toloza, Rafael Orlando (TAYLOR & FRANCIS LTD, 2004-08)
      The synthesis and phase characterization of three homologous series of liquid crystalline acrylic and methacrylic monomers, consisting of 21 new compounds are presented. They are based on omega-hexyloxy- and omega-undecy ...

    • Side chain liquid crystalline composites, occurrence of interdigitated bilayer smectic c phases 
      Vergara Toloza, Rafael Orlando; Soto Bustamante, Eduardo; González Henríquez, Carmen M.; Haase, Wolfgang (2011)
      We report on the results of X-ray investigations in two series of polymer monomer composites, PM6Rm-33 and PMnR12-33, which consist of mixtures of achiral liquid crystalline side chain polymers and their monomers. These ...
