ABSTRACT:
Polyurethane acrylate compositions are obtained by reacting 100 parts of a hydrophilic polyurethane resin in the presence of from about 10 to about 50 parts of an acrylate. The resulting products will form a hydrogel upon immersion in water and are permeable to gases, ions and other low molecular weight species. The hydrophilic polyurethane acrylate compositions may be molded to form shaped products that swell in water and have a variety of uses.
