  • Patent number: 7303821
    Abstract: This invention provides a chemically coated surface for the electrophoretic separation application. The surface comprises of block copolymers prepared from addition monomers selected from a group consisting of acrylates and its derivatives, metharylates and its derivatives, styrene and its derivatives, acrylamide, methacrylamide, dimethacrylamide, N-monosubstituted acrylamide, N-monosubstituted methacrylamide, N,N-bissubstituted acrylamide, N,N-bissubstituted methacrylamide, vinyl acetate, vinyl pyrolidone, vinyl ether, acrylic acid and methacrylic acid. This invention also provides a chemical process for making the chemically coated surface for the electrophoretic separation application. The process comprises: (a) contacting the support surface with a coupling agent solution, then (b) contacting the support surface with a first living radical polymerizing solution, and optionally (c) contacting the support surface with a second living radical polymerizing solution.

  • Patent number: 7247387
    Abstract: This invention provides a chemically coated surface for the plastics surface such as contact lens. The chemical surface coating comprises of at least one addition polymer prepared from addition monomers selected from a group consisting of acrylates and its derivatives, metharylates and its derivatives, styrene and its derivatives, acrylamide, methacrylamide, dimethacrylamide, N-monosubstituted acrylamide, N-monosubstituted methacrylamide, N,N-bissubstituted acrylamide, N,N-bissubstituted methacrylamide, vinyl acetate, vinyl pyrolidone, vinyl ether, acrylic acid and methacrylic acid. This invention also provides a chemical process for making the chemically coated surface on the plastics surface. The process comprises: (a) contacting the plastics surface with a coupling agent solution, then (b) contacting the plastics surface with a first living radical polymerizing solution, and optionally (c) contacting the plastics surface with a second living radical polymerizing solution.
