Process for obtaining expandable styrene polymers of fine particles, characterized in that the polymerization is carried out, at elevated temperatures, of styrene or mixtures of polymerizable monomer compounds containing excess styrene, in aqueous suspension in the presence of suspension stabilizers and agents of expansion, with the aid of polymerization initiators, and suspend monomers containing polymers in dissolved form, increasing the viscosity, at 25º C, of the solutions to values between 15 and 60,000 cP, and then carrying out the polymerization.
