Abstract
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.
