24. Phase-separated structures formed in polymer mixtures containing a thermotropic liquid crystalline copolyester as one component
The composition dependence of the phase-separated structures in the polymer mixtures consisting of a thermotropic liquid crystalline (LC) copolyester (X-7G) and poly(ethylene terephthalate) (PET) was investigated by means of polarized light microscopy. For this purpose the mixtures were solution-cast into thin films, followed by isothermal annealing at 270 °C. Although the final structure...

23. Ordered structure of thermotropic liquid crystalline polymers. 2. Observation of annihilation kinetics of wedge disclinations
The isothermal annihilation kinetics of wedge disclinations in the fully liquid crystalline state were investigated using thin film specimens of a thermotropic liquid crystalline copolyester prepared by a solution-cast method. The as-cast films which are vitrified, homogeneous and amorphous were first subjected to a temperature jump to appropriate temperatures and the coarsening of the liquid...

19. Elastic constant anisotropy, core structure wedge disclinations and optical texture of main-chain P-4-BCMU liquid crystals
The elastic constant anisotropy and the core structure of wedge disclinations with strengths s = ±½ of lyotropic liquid crystals of a soluble polydiacetylene, P-4-BCMU (Mw = 5.15 × 105, Mn = 2.16 × 105, and Mw/Mn = 2.4), in chloroform was studied. The Frank elastic constant anisotropy defined by ε = (k11 − k33)/(k11 + k33) for this polymer was determined by...

17. Lyotropic liquid crystals of the soluble polydiacetylene P-4-BCMU—a comparative investigation by means of optical and electron microscopy
The liquid crystalline properties of a concentrated solution of poly5,7-dodecadiyne-1,12-diol bis[(4-butoxycarbonyl)methyl)urethane] (P-4-BCMU) -a soluble polydiacetylene- in chloroform, beyond the critical concentration, have been investigated. Optical microscopy shows the anisotropic liquid crystal solution of P-4-BCMU in chloroform to be a polymer nematic. Disclinations with strengths of s=...

104. Liquid crystalline phase and gel-sol transitions for concentrated microcrystalline cellulose (MCC)/1-ethyl-3-methylimidazolium acetate (EMIMAc) solutions
Liquid crystalline (LC) phase transition and gel−sol transition in the solutions of microcrystalline cellulose (MCC) and ionic liquid (1-ethyl-3-methylimidazolium acetate, EMIMAc) have been investigated through a combination of polarized optical microscope (POM) observation and rheological measurements. Molecular LC phase forms at the 10 wt % cellulose concentration, as observed by POM, wher...
