The invention relates to a composition comprising: a) an acid monomer or oligomer of acrylic acid or of an acid derivative of acrylic acid or mixtures thereof; or a mixture of an ethylenically unsaturated monomer or oligomer and an acid monomer or oligomer of acrylic acid or of an acid derivative of acrylic acid; b) at least one radical initiator which forms a radical upon heating or upon irradiation with (UV) light in the range from 305 nm to 450 nm; and c) a compound of the formulae (I), (Ib) or (Ic) wherein Y represents a group that activates nucleophilic addition reactions at the adjacent double bond; X represents halogen or the anion of an aliphatic or aromatic monocarboxylic or dicarboxylic acid of 1-12 carbon atoms, of a monovalent or divalent oxo acid or of a complex acid; n represents 0 or 1; R1, R2, R3 independently of one another represent hydrogen, C1-C18alkyl, C3-C18alkyl interrupted by at least one nitrogen or oxygen atom, C3-C18alkenyl, C3-C18alkynyl, C7-C9phenylalkyl, C3-C12 cycloalkyl and C3-C12cycloalkyl containing at least one nitrogen or oxygen atom, which are substituted with at least one substituent selected from the group consisting of NO2, halogen, amino, hydroxy, cyano, carboxy, C1-C4alkoxy, C1C4alkylthio, C1C4alkylamino, di(C1-C4alkyl)amino and -O-C(=O)- C1C18alkyl; or phenyl or naphthyl or phenyl and naphthyl substituted with at least one substituent selected from the group consisting of C1-C4alkyl, C1-C4alkoxy, C1C4alkylthio, halogen, cyano, hydroxy, carboxy, C1-C4alkylamino and di)C1-C4alkyl)amino; or R1 and R2 together with the linking N, P or S-heteroatoms form a C3-C12 heteroycloalkyl radical; or R1 and R2 together form the groups: (Id); or (Ie) R1, R2 and R3 together form the groups (If) or (Ig). The invention relates also to acid macromomers and to their method of preparation by radically initiated polymerisation.
