The present invention is a free radical bulk polymerization process for the preparation of high molecular weight polymers from vinyl aromatic monomers, characterized in that the polymerization is conducted in the presence of a vinyl acid containing either a sulfur or phosphorus atom within the acid functional group.
La présente invention se rapporte à un procédé de polymérisation en masse alcaline, radicalaire libre s'appliquant à la préparation de polymères de poids moléculaire élevé à partir de monomères aromatiques vinyliques, ce procédé se caractérisant en ce que la polymérisation est effectuée en présence d'un acide vinylique contenant soit un atome de soufre, soit un atome de phosphore dans le groupe fonctionnel acide.
