Dispersion polymerizations of methyl methacrylate utilizing poly(1,1,-dihydroperfluorooctyl acrylate) as a steric stabilizer in supercritical carbon dioxide (CO 2 ) were carried out in the presence of helium. Particle size and particle size distribution were found to be dependent on the amount of in
Poly(2-hydroxyethyl methacrylate) particles in the micron size range were obtained by the dispersion polymerization. Cellulose acetate butyrate and dibenzoyl peroxide were used as steric stabilizer and initiator, respectively. The ultimate particle size could be adjusted by the selection of a suitab
Radical homopolymerizations and copolymerizations of 3-[tris(trimethylsilyloxy)silyl]propyl methacrylate (SiMA) in supercritical CO 2 were investigated. The homopolymer was obtained in CO 2 with a good yield. It was essentially insoluble in pure CO 2 at less than 500 bar at 65 Β°C but was soluble in
