1. A surface modifier of formula (I):


  • G-[B-A]n-B-G 



    (I)wherein(i) A is a soft segment comprising poly(hexamethylene carbonate)diol (PHCN);

    poly(ethylene-co-butylene)diol (PEB);

    1,6-hexanediol-orthophthalic anhydride polyester polyol (SPH);

    or neopentyl glycol-ortho phthalic anhydride polyester polyol (SPN);

    (ii) B is a hard segment comprising a urethane formed from a diisocyanate selected from 4,4′

    -methylene bis(cyclohexyl isocyanate)(HMDI);

    isophorone diisocyanate (IPDI);

    or m-tetramethylxylene diisocyanate (TMXDI); and

    (iii) G is a polyfluoroalkyl group;

    wherein n is an integer from 1 to 10,and wherein said surface modifier has a theoretical molecular weight of less than 10,000 Daltons.
