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