Abstract

L'invention concerne la préparation de dispersions de catalyseur. On prépare une dispersion aqueuse de catalyseurs oléosolubles stables à température superieure à - 5 degrés C des groupes peroxydes de dialcoyle diacyle ou diaryle ou de peroxydicarbonates et/ou des composés azoïques ou des anhydrides mixtes d'acides sulfoniques organiques et acides organiques et des peresters organiques et 0,01 à 5% en poids de colloides protecteurs et des émulsionnants sous l'action d'une puissante force de cisaillement La dispersion a une dimension granulométrique inférieure à 300 mu m et évite les inconvénients liés à l'utilisation de solvants organiques.
