Dimethyl ether (DME) has received a great deal of attention in industrial application. After DME prove to be the eco-friendly chemical material, more researchers take part in the DME application project. We found that a variety of monomeres can be dissolved in the compressed liquid phase of DME due to its chemically polar property. Compressed liquid DME can be used as polymerization media. To investigate monomers which can be used for synthesis of spherical polymer particle via dispersion polymerization, the experiments are performed with changing monomer. N-vinyl carbazole, 2-hydroxyethyl methacrylate, 2-hydroxypropyl methacrylate, acrylonitrile, glycidyl methacrylate, and Acrylic acid have been carried. The polymer morphology was characterized using a field emission scanning electron microscope (FE-SEM). The number-average particle size and the particle size distribution (PSD) were assessed with and image analyzer, TDI Scope Eye version 3.1, with FE-SEM images. |
