A (co)polymer structure comprising at least one portion of an acrylic, silicone, polyglycolic, polysaccharide or natural polymeric chain, comprising a plurality of functionalized units of general formula (I): wherein [C-A] is a portion of a polymeric or copolymeric chain selected from an acrylic silicone, polyglycolic, polysaccharide polymeric structure or from a natural polymer, and X is a functional group selected from one or more solfonic, carbossilic, amino acidic or epoxide groups to react at room temperature and in reaction conditions suitable for use on living beings and to form ionic or covalent bonds with keratin in absence of preemptive modifications of the polymer chain itself.
