Crosslinked poly(amino acids) useful as superabsorbent polymers and an improved process for preparing the crosslinked poly(amino acids) is disclosed. Use of polyaziridine and polyepoxide crosslinkers allows the production of superabsorbent polymers that is free of special handling steps required to process hydrogel materials using conventional preparation methods.
Divulguation concernant des poly(aminoacides) réticulés, utiles comme polymères superabsorbants; méthode améliorée pour préparer ces poly(aminoacides) réticulés. L'utilisation de réticulants à base de polyaziridine et de polyépoxyde permet de produire des polymères superabsorbants ne nécessitant pas les manipulations spéciales requises pour le traitement des matériaux de type hydrogel avec les méthodes de préparation classiques.
