Although it is possible to create a 100% amorphous structure, it is impossible to create a 100% crystalline structure as crystalline polymers always contain a decent number of amorphous polymers.

Crystallization of polymers is a process associated with partial alignment of their molecular chains. These chains fold together and form ordered regions called lamellae, which compose larger spheroidal structures named spherulites. Polymers can crystallize upon cooling from melting, mechanical stretching or solvent evaporation. Crystallization affects optical, mechanical, thermal and chemical properties of the polymer.

WebNov 4, 2024 · The molecular structure of a polymer — and the degree of crystallinity — has a tremendous impact on its properties. For example, crystalline polymers are generally opaque because the folded chains packed in the lamellae act to reflect light. Amorphous polymers, with their random entanglement of chains, tend to let light pass through them.
