  • Coating for biomedical devices
    Patent number: 7696259
    Abstract: A coating formulation for a substrate having abstractable hydrogen radicals is disclosed. The formulation includes a hydrophilic polymeric component comprising at least two polymeric species of differing molecular weights, an unsaturated hydrophilic monomer capable of free-radical polymerisation in the presence of a radical and a UV activatable compound capable of abstracting hydrogen radicals from the surface to be coated and from a polymeric specie of the hydrophilic polymeric component so as to initiate and promote the cross-linkage of the monomer to the surface and of the monomer or a propagating monomer chain to a polymeric specie of the polymeric component, and a suitable solvent to give the formulation a desired viscosity.

  • ORIENTED POLYMERIC SHEETS EXHIBITING DICHROISM AND ARTICLES CONTAINING THE SAME
    Publication number: 20070291345
    Abstract: Provided is an oriented polymeric sheet comprising a photochromic-dichroic material, wherein the sheet exhibits dichroism in an activated state. Also provided is a multilayer composite comprising at least a support layer; and an oriented thermoplastic polymeric sheet having two opposing surfaces and comprising a photochromic-dichroic material. The sheet exhibits dichroism in an activated state. At least one surface of the sheet is connected to at least a portion of the support layer. The present invention also relates to an optical element comprising the multilayer composite. Related methods also are disclosed.
