Webchain-folded model For crystalline polymers, a model that describes the structure of platelet crystallites. Molecular alignment is accomplished by chain folding that occurs at the crystallite faces. cis For polymers, a prefix denoting a type of molecular structure. WebThe folded chain model of the lamellae grown from dilute solution postulated in a polymer solid the inclusion of all the material in single crystals (one phase model). The amorphous x-ray diffraction pattern and the density defect were due to crystal defects, particularly to the chain folds at the crystal surfaces.
