Abstract

Η εφεύρεση αυτή αφορά σε μια μέθοδο για τον καθαρισμό και την ξήρανση μιας πολυμερούς υδρογέλης. Η εφεύρεση αυτή βασίζεται εν μέρει στην ανακάλυψη ότι η γρήγορη ξήρανση των πολυμερών υδρογελών μπορεί να απαλείψει το πρόβλημα των απαράδεκτων επιπέδων διαλυτών ολιγομερών που προκαλούνται από την παρατεταμένη θερμική επεξεργασία. Οι τεχνικές ταχείας ξήρανσης καθιστούν δυνατή την ξήρανση των υδρογελών που περιέχουν περισσότερο νερό απ' ότι θεωρούνταν παλαιότερα δυνατό, χωρίς απώλεια στην ποιότητα των προϊόντων. Επιπλέον, ανακαλύφθηκε ότι οι πολτοί που περιλαμβάνουν πολυμερείς υδρογέλες και μεγάλες ποσότητες νερού μπορούν να υποβληθούν σε ξήρανση ψεκασμού και αυτή η ξήρανση ψεκασμού μπορεί να διεξαχθεί με μόνο ελάχιστο σχηματισμό ολιγομερούς.
