Embodiments of the invention relate to a curable nucleus pulposus implant having water absorption and swelling capabilities, compositions for producing the curable nucleus pulposus implants, and methods of using the curable nucleus pulposus implants. The curable nucleus pulposus implant can be created from a polymer blend composition comprising a ratio of a curable material and at least one hydrophilic polymer. The resulting polymer blend composition may be used to generate curable nucleus pulposus implants to treat a number of disease and/or disorders, such as herniated discs. The curable nucleus pulposus implants may further contain polyelectrolytes and elastomer compounds, as well as pharmacological and biological agents.
