Dislocation Networks in Folded-Chain Polyethylene Crystals.
Interaction between the fold surfaces of polymer crystals can be strong enough to concentrate any mismatch in orientation into a network of dislocations. Direct observation of these networks by diffraction contrast electron microscopy yields strong evidence in favor of polymer crystallization by a regular chain-folding mechanism.
