Abstract

CE PROCEDE VISE A OBTENIR UNE DISSOLUTION RAPIDE DANS L'EAU D'UN GEL DE POLYMERE AQUASOLUBLE POUR PREPARER UNE SOLUTION AQUEUSE DILUEE DE CE POLYMERE. LE PROCEDE SELON L'INVENTION CONSISTE A EXTRUDER LE GEL10, A TRONCONNER LES BRINS OBTENUS49 ET A METTRE EN SUSPENSION DANS L'EAU34 LES PARTICULES RESULTANT DU TRONCONNAGE. ON SOUMET ENSUITE LA SUSPENSION A DE PUISSANTES FORCES DE CISAILLEMENT58, 60, 62 POUR FORMER UNE SUSPENSION DE PARTICULES TRES FINES. CETTE SUSPENSION EST MELANGEE A UN SUPPLEMENT D'EAU DANS DES CONDITIONS DE FAIBLE CISAILLEMENT, POUR FORMER LA SOLUTION AQUEUSE DILUEE DU POLYMERE. CE PROCEDE DIMINUE LA DEGRADATION DE CERTAINES PROPRIETES IMPORTANTES DU POLYMERE QUI SE PRODUIT DANS LES PROCEDES CONNUS.
