Abstract
Disclosed herein are cyclobutane-based crosslinking compounds that, when incorporated into acrylate-based polymeric materials, can produce toughened acrylate polymer networks. Also disclosed herein are polymers comprising the crosslinkers, methods of preparing toughened polymer networks using the crosslinkers, and methods of using the polymer networks.
