Abstract: A vinyl polymer obtainable by polymerisation of vinyl monomers in at least two steps, where, in the first step, from 5 to 95% by weight of the vinyl monomers are polymerised in an organic solvent or in the solid phase and, in the second step, from 5 to 95% by weight of the vinyl monomers are polymerised in the presence of the vinyl polymer obtained in the first step, likewise in an organic solvent or in the solid phase, with the proviso that the polymerisation in the second step is carried out on the conditions under which a mean molecular weight Mn which is at least 1000 higher than the vinyl polymer in the first step arises for the vinyl monomers of the second step in the absence of the vinyl polymers obtained in the first step.
