Continuous crosslinking of polymer gels

摘要

The present invention relates to a method for producing a cross-linked polymer gel. The method comprises the steps of (1) contacting a polymer with a cross-linking agent in a chamber under conditions suitable for producing a cross-linked polymer gel; and extruding the cross-linked polymer gel from the chamber. The method can, optionally, further include the step of fragmenting the cross-linked polymer gel of step (1) within the chamber to form cross-linked polymer gel particles. The cross-linked polymer gel particles can then be extruded from the chamber.
