Patent number: 8268952Abstract: The invention relates to supramolecular ionomers. i.e. polymers having quadruple hydrogen bonding units (4H-units) and ionic groups or ionogenic groups within their structure. The supramolecular ionomers can be dispersed or solubilized in water at high solids contents while maintaining low viscosities, facilitating easy use and processing of the resulting aqueous formulations. The aqueous supramolecular ionomer compositions have excellent film-forming properties. Moreover, the polymer materials have good mechanical properties after drying, as they are not tacky, show high elasticity and low or no creep.Type: GrantFiled: July 11, 2005Date of Patent: September 18, 2012Assignee: Suprapolix B.V.Inventors: Gaby Maria Leonarda Van Gemert, Ronny Mathieu Versteegen, Henricus Marie Janssen, Egbert Willem Meijer, Anton Willem Bosman

Patent number: 7622131Abstract: The invention relates to the synthesis of siloxane polymers containing self-complementary quadruple hydrogen bonding groups (4H-units). The resulting polymers show unique new characteristics that result from the reversible, physical interactions between the polysiloxane chains that are based on the (supramolecular) interactions between the 4H-units. The polysiloxanes in this invention show unprecedented bulk material properties and are used as gelling agents for silicone fluids. The resulting gels are clear and display good material properties, while having unparalleled high silicone fluid contents.Type: GrantFiled: June 9, 2005Date of Patent: November 24, 2009Assignee: Suprapolix B.V.Inventors: Anton Willem Bosman, Hendricus Marie Janssen, Gaby Maria Leonarda Van Gemert, Ronny Mathieu Versteegen, Egbert Willem Meijer, Rintje Pieter Sijbesma
