摘要： A water absorbent latex polymer foam produced by the process of combining a foamed latex polymer product with both a water absorbent polymer and chitin and drying that blend to form a foamable latex polymer containing both water absorbent polymer and chitin. The latex foams produced by this process are of great use, for example, with wound or surgical dressings.

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.

摘要翻译： 通过将泡沫胶乳聚合物产物与吸水性聚合物组合并干燥该共混物以形成含有吸水性聚合物的可发泡胶乳聚合物的方法制备的吸水胶乳聚合物泡沫体在本发明中公开。 通过该方法生产的乳胶泡沫在尿布，卫生巾，包装材料等中是非常有用的。 特别地，已经显示使用粒度小于约30微米的吸水聚合物来制备特别有效的吸收性胶乳泡沫。
