✦ Synopsis

The dispersion polymerization of styrene in supercritical CO 2 utilizing CO 2 -philic random copolymers was investigated. The resulting high yield of polystyrene particles in the micron-size range was formed using various random copolymers as stabilizers. The particle diameter was shown to be dependent on the composition of the stabilizer, and the weight percent of the stabilizer added to the system.
