P(A)m(F)n1(U)o1



  • (I)
    P(A)m(UFn2)o2



    (II)in whichP stands for a linear or branched, uncrosslinked homo- or heteropolymeric polymer component selected from the group consisting of;

    i) polyvinyl alcohols, polyvinyl amine, polyallyl amine, polyethylene imine, imides of polymaleic anhydride-alt-methyl vinyl ether or derivatives thereof;

    ii) linear polyethylene glycols, polypropylene glycols or derivatives thereof;

    iii) branched or star-branched polyethylene glycols;

    iv) polyureas, polyurethanes, polyesters, polycarbonates, polyhydroxycarboxylic acids or derivatives thereof, which are made up of diols/polyols and/or diamines/polyamines;

    v) polysaccharides as cellulose, starch, agarose, dextran, chitosan, hyaluronic acid or derivatives thereof;

    vi) polypeptides or derivatives thereof which are made of one or more various amino acid; and

    vii) branched polyols based on glycidol;

    A stands for identical or different phosphorus-containing groups bonded to P,m stands for a number from 3 to 1000,F stands for identical or different functional groups bonded directly or indirectly to P, which are present in addition to A,n1 stands for a number from 1 to 1000,n2 stands for a number from 1 to 100,U stands for identical or different, linear or branched, uncrosslinked oligomeric or polymeric segments, made up of identical or different monomers, which are bonded to P,o1 stands for a number from 0 to 1000,o2 stands for a number from 1 to 1000.
