Reinforced, laminated, impregnated, and materials with composite properties as cross linked polyvinyl alcohol hydrogel structures in bulk or cellular matri x forms that can take essentially any physical shape, or can have essentially any size, degree of porosity and surface texture. They have a wide range of physical properties, unusual and unique combinations of physical properties and unique responses to stress fields, which allows for their use in many en d use applications. |
