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 an amine functional silane monomer precursor or an amine functional polysiloxane monomer precursor and {HEAD ~ a derivative} of carbonic acid or {TAIL ~ a cyclic lactone}
