Abstract:
A process for coating a material surface comprising the steps of:(a) applying to the material surface at least one 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 preccursor for carbene or nitrene formation, wherein the comb-type polymer comprises units of formula wherein R is hydrogen or C1-C4-alkyl,A is a radical of formula â€”C(O)â€”Xâ€”â€ƒâ€ƒ(2a), â€”C(O)â€”Oâ€”(CH2)â€”CH(OH)â€”CH2â€”Xâ€”â€ƒâ€ƒ(2b), â€”C(O)â€”NHâ€”(alkâ€²)â€”C(O)â€”Xâ€”â€ƒâ€ƒ(2c), â€”C(O)â€”Oâ€”(alkâ€³)â€”NHâ€”C(O)â€”Xâ€”â€ƒâ€ƒ(2d), â€”C(O)â€”(alkâ€³)â€”X1â€”C(O)â€”â€ƒâ€ƒ(2e), â€”C(O)â€”NHâ€”C(O)â€”Xâ€”â€ƒâ€ƒ(2f), â€”(alkâ€²â€³)aâ€”Xâ€”Oâ€”X1â€”â€ƒâ€ƒ(2g) â€”Xâ€”(alkâ€²)â€”X1â€”â€ƒâ€ƒ(2h), â€”Xâ€”C(O)â€”â€ƒâ€ƒ(2i), â€”(alkâ€²â€³)â€”C(O)â€”Xâ€”â€ƒâ€ƒ(2j) orâ€”(alkâ€²â€³)â€”Xâ€”C(O)â€”â€ƒâ€ƒ(2k), wherein (alkâ€²) is C1-C6-alkylene, (alkâ€³) is C2-C12-alkylene, (alkâ€²â€³) is C1-C9-alkylene, D is a group â€”C(O)â€” or â€”C(S)â€” and &egr; is 0 or 1,X and X1 are each independently a group â€”Oâ€” or â€”NR1â€”, wherein R1 is hydrogen or C1-C4-alkyl, (oligomer1) is the radical of (i) a hydrophilic telomer which is derived from one or more different copolymerlzable vinyl monomers, (ii) the radial of an oligosaccharide, (iii) the radical of an oligopeptide, or (iv) the radical of a polyalkylene oxide, Q is a radical comprising a triggerable precursor for carbene or nitrene formation, r is an integer from 1 to 4; and m is an integer &gE;1; (b) fixing the polymer(s) onto the material surface using UV or visible light.
