A new styrene-maleic anhydride-based dispersing resin is described and its utility in preparing waterbased metallic and organic pigment dispersions and printing inks is demonstrated. This resin contains amic acid functionality, groups that are possible to form only with anhydride-containing resins. A unique combination of properties is exhibited by this resin, including neutral pH, high water s...

This work results from our attempts to solve Boltzmann–Sinai’s hypothesis about the ergodicity of hard ball gases. A crucial element in the studies of the dynamics of hard balls is the analysis of special hypersurfaces in the phase space consisting of degenerate trajectories (which lack complete hyperbolicity). We prove that if a flow-invariant hypersurface J in the phase space of a semi-disper...

The 1-hexadecyl-3-vinylimidazolium bromide (hvimBr), a water-soluble long-chain imidazolium ionic liquid (IL) with surfactant properties, showed the ability to produce stable homogeneous aqueous dispersions of pristine Single-Walled Carbon Nanotubes (SWNTs). The purpose of this study is the improvement of SWNT dispersing ability by assessing the effect of different groups in position 3 of the i...
