conformational melting

https://doi.org/10.1351/goldbook.12751
Step-like increase in the conformational entropy of macromolecules, or parts of macromolecules.
Notes:
  1. This melting can be caused by a temperature change or by interaction with a solvent.
  2. Conformational melting normally occurs along with crystalline melting in a partially crystalline polymer.
Example: A helix–coil transition is an example of conformational melting.
