Abstract

A process for the production of a particulate foamable polyvinylaromatic resin, characterized in that it consists of a desired range of particle sizes that comprises the polymerization of a vinylaromatic monomer in an aqueous suspension system to produce polyvinylaromatic resin beads, separating a fraction of beads having a given range of particle sizes from the rest of the beads, and incorporating a volatile liquid blowing agent into the separated bead fraction at a temperature above the softening point of the resin so that under such conditions, resin particles having the desired size range.
