Abstract

L'invention est relative à un procédé de préparation de polymères ou copolymères du styrène par polymérisation en suspension aqueuse. Le procédé de l'invention consiste à utiliser comme stabilisateur de suspension un phosphate de calcium précipité chauffé en dispersion dans l'eau entre 70 degrés C et 130 degrés C pendant deux heures au moins. Les polymères du styrène obtenus peuvent être expansés.
