Abstract

IL S'AGIT DE SUSPENSIONS STABLES DE POLYMERES DISSOUS DANS L'EAU OU GONFLES DANS L'EAU DANS DES SOLVANTS ORGANIQUES QUI SONT AU MAXIMUM PARTIELLEMENT MISCIBLES AVEC L'EAU. ELLES ONT UNE TENEUR EN MATIERES SOLIDES D'AU MOINS 35 EN POIDS PAR RAPPORT A LA SUSPENSION TOTALE ET UNE VISCOSITE INFERIEURE A 3000MPA.S, DE PREFERENCE INFERIEURE A 1000 (DETERMINEE D'APRES LA METHODE DE BROOKFIELD). POUR LES PREPARER, ON HOMOGENEISE UNE PHASE QUI CONTIENT AU MOINS UN MONOMERE HYDROSOLUBLE, UN INITIATEUR DE POLYMERISATION ET DE L'EAU (PHASE MONOMERE) AVEC UNE SECONDE PHASE CONTENANT LE SOLVANT ORGANIQUE QUI EST AU MAXIMUM PARTIELLEMENT MISCIBLE AVEC L'EAU ET AU MOINS UN EMULSIONNANT (PHASE HUILEUSE), ET ON FAIT POLYMERISER L'EMULSION FORMEE SUIVANT LE PROCEDE D'ADDITION DE L'EMULSION. APPLICATIONS DE CES SUSPENSIONS: APPRETS, EPAISSISSANTS, AGENTS DE FLOCULATION ET SIMILAIRES.
