Abstract

Procédé amélioré de préparation en continu d'émulsions à phase interne élevée, c'est-à-dire, dont le rapport entre la phase aqueuse et la phase huileuse est relativement élevé (HIPE) et qui sont polymérisées de façon que des matériaux en mousse polymère microporeuse à cellules ouvertes, capables d'absorber des fluides aqueux, particulièrement des fluides corporels aqueux tels que l'urine soient obtenus. L'amélioration consiste à faire recirculer une partie (égale ou inférieure à 50%) de l'émulsion retirée de la zone de mélange dynamique du processus en continu. Ceci permet d'augmenter l'uniformité de l'émulsion obtenue à la fin dudit processus, sous l'effet de la dispersion homogène des gouttelettes d'eau dans la phase huileuse. Ceci permet également d'améliorer la stabilité de l'émulsion HIPE et d'agrandir la plage de température de coulée et de durcissement de ladite émulsion pendant sa polymérisation subséquente en émulsion.
