Graft copolymer for treating surface structures

The invention concerns graft copolymers, useful for the treatment of leather, comprising monomers of the formula ##STR1## grafted onto a base polymer comprising monomers of the formula ##STR2## wherein R.sub.1 and R.sub.2 stand for a hydrocarbon group having 2 to 24 carbon atoms, with the proviso that the groups R.sub.1 and R.sub.2 have van der Waals volumes which differ from one another by less than 30 percent.
