Abstract

A process for obtaining styrene polymers and copolymers, which can be transformed into fluff products, characterized in that the polymers or copolymers of styrene, in the form of small particles and in an aqueous suspension, are heated, together with an agent for the swelling based on volatile hydrocarbons, at a temperature of 110 to 115º, stirring at the same time, and after cooling the particles obtained in the form of beads are separated.
