Abstract
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 a derivative of carbonic acid or a cyclic lactone.
