  • Patent number: 6878399
    Abstract: The invention relates to a process for coating a material surface, comprising the steps of: (a) providing an inorganic or organic bulk material; (b) providing one or more polyionic materials at least one of them comprising covalently bound initiator moieties for radical polymerization; (c) applying the polyionic material of step (b) to the bulk material of step (a), thereby forming a hydrophilic layer on the bulk material surface; and (d) graft polymerizing a hydrophilic monomer or macromonomer onto said polyionic material. The coated articles that are obtainable by the process of the invention have desirable characteristics regarding adherence to the substrate, durability, hydrophilicity, wettability, biocompatibility and permeability and are thus useful for the manufacture of biomedical articles such as ophthalmic devices.
    Type: Grant

  • Patent number: 6835410
    Abstract: The invention relates to a process for coating a material surface comprising the steps of: (a) providing an inorganic or organic bulk material having covalently bound to its surface initiator moieties for radical polymerization; (b) graft polymerizing a hydrophilic ethylenically unsaturated macromonomer from the bulk material surface in the presence of a biocompatible hydrophilic polymer being devoid of polymerizable ethylenically unsaturated groups and thereby entrapping said hydrophilic polymer within the polymer matrix formed by the polymerization of the macromonomer. Composite materials obtainable according to the process of the invention have desirable characteristics regarding adherence to the substrate, durability, hydrophilicity, wettability, biocompatibility and permeability and are thus useful for the manufacture of biomedical articles such as ophthalmic devices.

  • Patent number: 6730366
    Abstract: The invention relates to a process for coating a material surface comprising the steps of: (a) applying to the material surface one or more different comb-type polymers comprising a polymer backbone and side chains pendently attached thereto, wherein at least a part of the side chains carry a triggerable precursor for carbene or nitrene formation; and (b) fixing the polymer(s) onto the material surface using heat or radiation, in particular radiation such as UV or visible light. The polymers of the invention are useful for the modification of material surfaces and are particularly suitable for providing biomedical articles such as contact lenses with a hydrophilic coating.

  • Patent number: 6589665
    Abstract: The invention relates to novel composite materials comprising (a) an inorganic or organic bulk material having attached to its surface at least one polyionic material that comprises covalently bound initiator moieties for radical polymerization; and (b) a hydrophilic surface coating obtainable by applying one or more different ethylenically unsaturated hydrophilic monomers or macromonomers to the bulk material surface provided with the initiator radicals and polymerizing said monomers or macromonomers. The composite materials of the invention have desirable characteristics regarding adherence to the substrate, durability, hydrophilicity, wettability, biocompatibility and permeability and are thus useful for the manufacture of biomedical articles such as ophthalmic devices.
