  • Method of rendering substrates water repellent using hyperbranched polymers containing silicon atoms
    Patent number: 6103848
    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.
    Type: Grant
    Filed: June 17, 1999
    Date of Patent: August 15, 2000
