Disclosed is a process for coating a polymer substrate, by grafting: (i) a mixture of (A) a monomer of the general formula Formula I R-(A)a (wherein R stands for an aliphatic unsaturated radical with the valency a; (A) stands for an acid group or a salt thereof; a stands for 1, 2, or 3), and (B) a cross-linking vinyl monomer (B monomer) that contains at least two olefin double bonds or (ii) a mixture of the cross-linking vinyl monomer B and a polymer derived from the (A) monomer (polymer C), onto the polymer substrate, wherein the polymer substrate has been activated prior to the grafting process or an initiator is used and the grafting is initiated by electromagnetic irradiation or thermally. Articles that have been coated according to the present invention are suitable for use in the fields of food and beverage technology, water technology, biotechnology, health and hygiene , and in particular medical technology.
