Abstract
Process for obtaining polymeric suspensions, characterized in that the polymerization is carried out, in aqueous suspension, at elevated temperatures, of styrene or mixtures of styrene and other polymerizable monomer compounds, with the aid of polymerization catalysts and in the presence of suspension stabilizers, increasing the pressure inside the reaction vessel, at the moment of reaching a turning of conversion to which there is no confluence of the polymer particles, injecting inert gases, at a value at least one fifth higher than the initial pressure .
