Title:
SELF-HEALING POLYMER NETWORK CONTAINING PHYSICAL CROSSLINKER, COMPOSITION THEREFOR, AND OPTICAL ELEMENT COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2018/212511
Kind Code:
A1
Abstract:
Provided are: a self-healing polymer network containing a physical crosslinker; and a composition therefor. The self-healing polymer network comprises self-healing monomers having a first polymerizable functional group and at least one urethane group, urea group, or amide group chemically linked to the first polymerizable functional group, and thus has a polymer having a main chain, which is obtained by polymerization of the first polymerizable functional group, and a plurality of side chains, which are suspended on the main chain and have at least one urethane group, urea group, or amide group. In addition, the self-healing polymer network has a physical crosslinker, which crosslinks at least one urea group, urethane group, or amide group provided in each of the side chains to crosslink the polymers, wherein the physical crosslinker is an alcohol mixture containing at least two of monools, diols, triols, and tetravalent or higher polyols.
