摘要:
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.
