Abstract

Nitroxide-mediated dispersion polymerization of styrene in supercritical carbon dioxide has been performed successfully at 110°C using a new polymeric so-called inistab species, which fulfils the dual functions of an initiator and a colloidal stabilizer. The inistab species comprised a poly(dimethylsiloxane) block and a polystyrene block end-capped with the nitroxide N-tert-N-butyl-N-[1-diethylphosphono-(2,2-dimethylpropyl)] nitroxide (SG1). The dispersion polymerization resulted in sub-micron sized polymer particles and polymers of narrow polydispersity.
