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: 8765879
    Abstract: To provide a modified recycled polyester resin that has stable moldability, is capable of producing as a by-product only a small amount of gel-like material during the process of modification to allow stable cross-linking reaction, and can prevent the possibility of recleavage, and to provide a molded article using the same. The modified recycled polyester resin contains a recycled PET resin having a carboxyl group, and a modifying agent having an epoxy group and an oxazoline group, ends of the carboxyl group of the recycled PET resin being modified with the modifying agent, wherein a mole ratio between the oxazoline group and the epoxy group is within a range of 100:90 to 100:0.01, and an additive amount of the modifying agent is 0.001 to 15 parts by mass with respect to 100 parts by mass of the recycled PET resin.
