摘要： 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.

摘要： 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.
