Abstract

La présente invention concerne un procédé de production d'une résine très absorbante présentant d'excellentes propriétés d'absorption, et plus particulièrement un procédé de production d'une résine très absorbante dans lequel les problèmes associés à un processus peuvent être évités par la suppression efficace de l'initiation d'une réaction de polymérisation dans une conduite avant l'introduction dans un réacteur de polymérisation.
