reorganization

in polymers
The molecular process by which (i) amorphous or poorly ordered regions of a polymer specimen become incorporated into crystals, or (ii) a change to a more stable crystal structure takes place, or (iii) defects within the crystal decrease.
Notes:
  1. Secondary crystallization may be involved in the reorganization process.
  2. Reorganization may result from annealing.
  3. Points (i) and (ii) above may also be called crystal perfection.
