Abstract
The present invention provides protein-containing polymers and a general method of incorporating biologically active proteins into a polymer matrix via copolymerization in organic solvents. Preferably, the protein is an active enzyme which maintains its activity in the polymeric matrix. The proteins are first solubilized in organic solvents by covalent attachment of a modifying moiety such as a polyalkylene oxide. The polyalkylene oxide is functionalized with a functional group enabling copolymerization in organic solvents with an organic-soluble comonomer.
