WebAmorphous polymers can be defined as polymers that do not exhibit any crystalline structures in X-ray or electron scattering experiments. They form a broad group of materials, including glassy, brittle and ductile polymers. In contrast to the word “amorphous”, weak domain-like or globular structures can exist, which are often only visible ... WebJul 9, 2024 · Crystalline and Amorphous Polymers. When applied to polymers, the term crystalline has a somewhat ambiguous usage. A synthetic polymer may be loosely described as crystalline if it contains regions of three-dimensional ordering on atomic (rather than macromolecular) length scales, usually arising from intramolecular folding …
