Abstract
A water absorbent latex polymer foam produced by the process of combining a foamed latex polymer product with a water absorbent polymer and drying that blend to form a foamable latex polymer containing a water absorbent polymer is disclosed in this invention. The latex foams produced by this process are of great use, for example, within diapers, sanitary napkins, packaging materials, and the like. In particular, the use of water absorbent polymers with particle size less than about 30 microns has been shown to produce particularly effective absorbent latex foams.

Newly developed polymeric materials are presented in a form of pellet, thread, sponge, rubber, or plate acting as a damper for shear mode and an absorber against outside noise. These materials provide multiple functions of damping, sound absorbency and insulation performance at audio frequency.

6537934 - Adhesive compositions and composite materials

A composite material is formed from a flexible porous hardening foam (e.g. polyurethane) and an adhesive composition which sets to a water-resistant film and contains a water-absorbent filler (e.g. fumed silica) in an amount such that the film is water absorbent. The adhesive reinforces the foam while preserving its porosity and absorbency. The material is suitable for shoe insoles and handgrips. The adhesive may be primarily in a surface layer e.g. of cloth (14) applied to the foam (12); or the foam (22) may be saturated with the composition prior to curing.
