Abstract:
A method of processing a water-dispersible, polymer-based material in a bath of a water-based solution includes providing a molten water-dispersible polymer material having monovalent cations. The water-dispersible polymer is introduced into a water bath comprising multivalent salt dissociated in the water bath into multivalent cations and anions. The water-dispersible polymer is retained within the water bath with the dissociated multivalent cations to quench the water-dispersible, polymer-based material while the monovalent cations proximate a surface of the water-dispersible polymer are exchanged with multivalent cations to form a barrier that temporarily resists dispersion of the water-dispersible, polymer-based material within the water bath. The method includes removing the water-dispersible polymer from water bath after the exchange step.
