Substrates are rendered water repellent by applying to the substrate a hyperbranched polymer containing a silicon atom made by polymerizing a derivatized aminofunctional organosilicon monomer which is the reaction product of {TAIL ~ an amine functional silane monomer precursor} or an amine functional polysiloxane monomer precursor and a derivative of carbonic acid or {HEAD ~ a cyclic lactone}
