摘要:
A slurry or cake is converted to a crumbly state by admixture, in the absence of a polymeric binder, with water swellable, cross-linked, non-sticky, wholly synthetic polymer particles formed of a polymer of acrylic acid (as free acid or water soluble salt) with cross-linking agent and, optionally, acrylamide and/or other monomers.
