Abstract

The present invention relates to a process for removing unreacted gaseous monomers from a solid polymer product.
In the present invention the dried polymers are subject to alternating stages of positive pressure and near vacuum conditions, with unreacted gaseous monomers being removed from the reacted polymers during the vacuum stage.
