A novel twin-tail quaternary ammonium hydrocarbon surfactant was synthesized using oligovinyl acetate (OVAc) as the CO2-philic unit.  It was then shown that this stabilizer is an emulsifier for water and an efficient stabilizer for the dispersion polymn. of pyrrole in supercrit. carbon dioxide (scCO2).
