Resumo

The dispersion polymerization of styrene in supercritical CO2 utilizing CO2-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. © 2000 John Wiley & Sons, Inc.
