Abstract:
An absorbent structure formed from a process of providing water-swellable material that includes water-swellable polymer particles, which are coated with a coating agent. The coating agent is a phase-separating elastomeric material that has a first and second glass transition temperature. The coated water-swellable polymer particles are able to swell without breakage of the coating.
