摘要：
This invention relates to improved absorbent structures containing improvedwater-swellable material that can significantly withstand deformation by anexternal pressure, thus showing improved liquid handling properties. Inparticular, this invention relates to absorbent structures comprising water-swellable material with an improved absorbent capacity/ permeability balance.The water-swellable material is typically in the form of particles, whichcomprise a core of water-swellable polymer (s) and a shell of said elastomericpolymer(s), preferably selected polyetherpolyurethanes, whereby the water-swellable material is such that it can withstand deformation due to externalpressure. The invention also relates to diapers, adult incontinence articlesand sanitary napkins comprising said absorbent structure of the invention.
