Area of Science:

• Polymer Science
• Materials Science
• Computational Chemistry

Background:

• Reversibly bonding polymers form dynamic covalent bonds at chain ends.
• These bonds impart unique properties like self-healing and thermal tunability.
• Previous computational studies were limited by complexity.

Purpose of the Study:
