  • Patent number: 11529648
    Abstract: The disclosure relates to a self-healing laminate composition. The composition includes a first, self-healing layer with a self-healing polymer and a second, mechanical layer adjacent to the first layer. The second layer includes any desired polymer, for example a crosslinked polymer, a thermoplastic polymer, or a functional thermoset polymer. Self-healing polymers with dynamic covalent bonds are suitable, for example those with dynamic urea bonds and/or dynamic urethane bonds. A self-healing polymer that is damaged can undergo autonomous repair when separated surfaces re-contact each other due to the soft nature of the self-healing polymer, whereupon reversible bonds can reform to rejoin and repair the damaged self-healing polymer. When the self-healing laminate according to the disclosure is damaged, the self-healing mechanism of the first layer can cause the repair of both layers.

  • Patent number: 8535874
    Abstract: Provided is a novel fluorene-based polymer having urethane bonds and a method for preparing the fluorene-based polymer. According to the method, a diol compound is condensed with a diisocyanate instead of an acid dianhydride, and then an acid anhydride is reacted with the reaction mixture to introduce desired acid groups into the final polymer. Further provided is a negative-type photosensitive resin composition comprising of the fluorene-based polymer as a binder resin. The composition exhibits improved chemical resistance, good development margin and high sensitivity due to presence of the acid groups despite the low molecular weight of the fluorene-based polymer.
