Key words: supercritical carbon dioxide, methylmetacrylate, styrol, co-polymers, polymer nanocomposites
We report about thin polymer particles synthesis based on radical co-polymerization of methylmetacrylate and styrol in supercritical СO2 medium. We utilize supercritical СO2 soluble polydimethylsiloxan metacrylate as a dispersion agent, which allow us to produce almost monosize particles. Co-polymer spherical powder, with typical sizes about 1 micron and molecular weight Mw ~ 36000 has higher thermostability compare to similar Mw polymethylmetacrylate. We have shown the possibility of mechanical and hydrophobic co-polymer properties controlled changes with varying of monomer charge ratio.
