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.
