Abstract
Porous, absorbent macrostructures having improved fluid handling capabilities that include inter-particle bonded aggregates, and are useful in absorbent articles, such as diapers, adult incontinence pads and sanitary napkins, are disclosed. The inter-particle bonded aggregates of these macrostructures are made from mixtures of particulate absorbent polymers having different fluid handling properties, different shapes, or both. These macrostructures can be made from a wider variety of hydrogel-forming absorbent polymers without sacrificing desired fluid handling properties, and without being prone to gel blocking.
