Five novel amldate crown ethers were deslgned and synthesized. The structures of all the compounds synthesized are characterized by elementary analysis, IR, MS and 1H NMR spectroscopy. The liquld crystal properties of three compounds 4-6 have been characterized by DSC.
This paper discusses the factors influencing pigment dispersion, such as pedicle size and its distribution, the dispersingart, dispersant and so on. The theories of steric stabilization, deplction flocculation and depletion stabilization are suitable forinterpreting experimental results in UV-cured ink. The UV-cured ink of good dispersion is obtained.
