Abstract: Preparation of styrene polymers containing a propellant by polymerisation of styrene with comonomers, in aqueous suspension, with addition, (at start or during polymerisation) of amphiphilic organic emulsifying agent containing hydrophilic and hydrophobic groups, or a polymer carrying a polar group, (miscible in water), so the suspended styrene droplets contain finely distributed water particles.
