WebNov 20, 2024 · Crystallinity in polymers is more complex than in other materials because of the long polymer chains. In some areas, the polymer chains align and pack together to form crystals; in other areas, the chains are disordered and cannot pack together, so semi-crystalline polymers tend to have crystalline regions dispersed within amorphous material. WebJul 9, 2024 · Few synthetic polymers are entirely crystalline. The crystallinity of polymers is characterized by their degree of crystallinity, ranging from zero for a completely non-crystalline polymer to one for a theoretical completely crystalline polymer.
