Dispersion Polymerization of Acrylonitrile in Supercritical Carbon Dioxide

Herein we report the successful dispersion polymerization of acrylonitrile in carbon dioxide using a block copolymer consisting of polystyrene and poly(1,1-dihydroperfluorooctyl acrylate) as a stabilizer. Submicron-sized polyacrylonitrile particles were obtained. The initial concentrations of acrylo...

Zusammenfassung:	Herein we report the successful dispersion polymerization of acrylonitrile in carbon dioxide using a block copolymer consisting of polystyrene and poly(1,1-dihydroperfluorooctyl acrylate) as a stabilizer. Submicron-sized polyacrylonitrile particles were obtained. The initial concentrations of acrylonitrile and the stabilizer and the reaction pressure had some effects on the resulting size of the colloidal particles.
