    Abstract: A method for producing and coating a specific surface of moulded plastic object, comprising the steps of: a) producing said object in a manufacturing machine according to per se known methods; b) transferring said object into and through a tunnel comprising at least three, optionally four or five consecutive partially separated chambers in the direction A to E, where chambers A and E each comprise an opening to the surroundings, the consecutive chambers of the tunnel having a controlled atmosphere obtained by injection, said injection of controlled atmosphere being set up in such a way that the net air transport in said tunnel is directed from chamber D to A and out to the surroundings as well as from chamber E and out to the surroundings, during which transferring the object receives a treatment comprising: applying, in chamber A, a microemulsion comprising a cleaning agent to said specific surface; rinsing, in chamber B, said specific surface with a volatile rinsing agent capable of removing said microemulsion from said specific surface; optionally drying, in optional chamber C, in such a way that said volatile rinsing agent is removed from said specific surface; and optionally adjusting, in optional chamber D, the temperature of said specific surface to the temperature of subsequent coating step; and c) transferring said moulded plastic object from any of chambers B -D to chamber E and coating said specific surface according to per se known methods.

    Abstract: The invention relates to a process for coating a material surface comprising the steps of: (a) reacting the material surface with a compound of formula (1), wherein the variables are as defined in the claims; (b) reacting the so modified surface with a functional polymerization initiator having a functional group that is co-reactive to L2 or L2'; and (c) applying one or more different ethylenically unsaturated hydrophilic monomers or macromonomers to the bulk material surface obtainable according to step (b) and polymerizing said macromonomers, thereby providing a preferably hydrophilic surface coating onto the material surface. Composite materials obtainable according to the process of the invention have desirable characteristics regarding adherence to the substrate, durability, hydropholicity, wettability, biocompatibility and permeability and are thus useful for the manufacture of biomedical articles such as ophthalmic devices.
