  • Patent number: 11548962
    Abstract: A self-healing polymer network containing a physical crosslinking agent, a composition therefor, and an optical element comprising the same is provided. The self-healing polymer network comprises a polymer derived from monomers including self-healing monomers each having a first polymerizable functional group and at least one of urethane, urea, or amide group chemically linked to the first polymerizable functional group, wherein the polymer has a backbone formed by polymerizing the first polymerizable functional groups of the self-healing monomers and a plurality of side groups each having at least one of urethane, urea, or amide group chemically linked to the backbone. In addition, the self-healing polymer network comprises a physical crosslinking agent which is an alcohol mixture having at least two of monool, diol, triol, and tetraol or the higher polyol and crosslinking the polymer by physically crosslinking the urethane, urea, or amide group of the side groups.
