Abstract:
1. Copolymers of the formula: in which (A) each independently is a unit of the formula (B) each independently is a unit of the formula and (C) each independently is a unit of the formula where X each independently is an alkylene radical having 1 to 700 carbon atoms, which is unsubstituted or substituted by fluorine, chlorine, C Y each independently is a divalent hydrocarbon radical having 1 to 30 carbon atoms in which non-adjacent methylene units are optionally replaced by O, or is the radical (CH Z each independently is a divalent hydrocarbon radical which has 1 to 30 carbon atoms and is unsubstituted or substituted by fluorine or chlorine, D each independently is hydrogen or a monovalent, unsubstituted or substituted hydrocarbon radical, E each independently is an oxygen atom or an amino group —ND-, R each independently is a monovalent hydrocarbon radical which has 1 to 20 carbon atoms and is unsubstituted or is substituted by fluorine or chlorine, R R G each independently is defined as for Z, R″ is a hydrogen atom or a radical —CO—NH-Z-NCO, R′ if R″ is hydrogen atom, is a radical HND-Y—Si(OR n each independently is an integer from 1 to 4000, o each independently is 0, 1 or 2, a is an integer of at least 1, b is an integer of at least 1, c is 0 or an integer of at least 1, with the proviso that per molecule at least one radical R
