Abstract
Particulate absorbents of a water-insoluble water-swellable polymer having a gel capacity of at least 10 are immobilized with a composition comprising the absorbent in a liquid polyhydroxy organic compound. The composition may be employed by applying to an appropriate surface and subjecting the liquid film to solidifying conditions. The solidified film product has high absorptive capacity and is free of undesirable movement when positioned in absorbent articles. A foam product having both absorptive and cushioning properties is prepared from a solid, particulate, water-insoluble, water-swellable polymer having a gel capacity of at least 10, a solid, particulate blowing agent, and a liquid polyhydroxy organic compound. Foamable compositions and articles employing the foam are also described.
