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.
Secondary crystallization may be involved in the reorganization process.
Reorganization may result from annealing.
Points (i) and (ii) above may also be called crystal perfection.
