A process for the preparation of superabsorbers is disclosed. The process entails subjecting a polyacrylonitrile precipitation polymer alkaline hydrolysis to obtain a hydrolysis product. The hydrolysate that may optionally be neutralized is dried and ground and optionally modified by crosslinking of its surface. The inventive superabsorber is suitable for the preparation of nappies, incontinence articles, water-storage materials and electric cable coverings.

Um processo para a preparação dos superabsorbers é divulgado. O processo envolve sujeitar um hydrolysis alcalino do polímero polyacrylonitrile da precipitação para obter um produto do hydrolysis. O hydrolysate que pode opcionalmente ser neutralizado é secado e moído e modificado opcionalmente crosslinking de sua superfície. O superabsorber inventive é apropriado para a preparação dos nappies, dos artigos do incontinence, dos materiais do água-armazenamento e dos coverings do cabo elétrico.
