27. Process and mechanism of phase separation in polymer mixtures with a thermotropic liquid crystalline copolyester as one component
The phase separation and the coarsening process of polymer mixtures with a thermotropic liquid crystalline polymer (LCP) as one component are investigated. The LCP used is a main-chain type copolyester X-7G, comprised of p-hydroxybenzoic acid (60 mol %) and ethylene terephthalate (40 mol %) units. The isotropic, transparent, and homogeneous test specimens of the 50/50 mixtures of X-7G and po...

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...

A facile one-step synthesis to cross-linked polymeric nanoparticles as highly active and selective catalysts for cycloaddition of CO2 to epoxides2
A very convenient one-step synthesis to cross-linked polymeric
nanoparticles by conventional radical copolymerization without
the addition of stabilizers or surfactants was explored. Moreover,
these nanoparticles exhibited excellent stability, activity and
selectivity in the cycloaddition reaction of CO2 to epoxides and
could be separated from the products easily and reused.

A one-pot synthetic approach to prepare palladium nanoparticles embedded hierarchically porous TiO2 hollow spheres for hydrogen peroxide sensing
A simple one-step method to fabricate hierarchically porous TiO2/Pd composite hollow spheres without any template was developed by using solvothermal treatment. Pd nanoparticles (2–5 nm) were well dispersed in the mesopores of the TiO2 hollow spheres via in-situ reduction. In our experiment, polyvinylpyrrolidone played an important role in the synthetic process as the reducing agent and the conne...

Photografting of unable-to-be-irradiated surfaces. I. Batch vapor-phase process by one-step method
Surfaces unable-to-be-irradiated are those that could not be directly exposed to UV irradiation because of their irregular structure or instability under UV irradiation. It is difficult to conduct surface photografting on these kinds of surfaces with conventional photografting methods. Here, a novel one-step surface photografting method is introduced, by which some monomers were smoothly graf...
