Self-healing polymer

    Why not create a self-healing polymer able to repair itself repeatedly while also maintaining strength and stability?
    The polymer will be cross-linked through trithiocarbonate units, which will be able to restructure under UV light. The light will break one carbon-sulfur bond which will produce two very reactive radicals, which will form new carbon-sulfur bonds while breaking others to form new radicals. The chain reaction will be halted when two radicals react with each other.
    Such polymers could both increase the durability of products and make repairs easier.
