Atactic polymer

Definition

An atactic polymer is a type of synthetic polymer where the substituent groups are randomly arranged on the main polymer chain. This lack of regularity in the arrangement of side chains leads to polymers that are usually amorphous, lacking a well-defined crystalline structure.

Related terms

Isotactic Polymer: A polymer with all substituent groups positioned on the same side of the polymer backbone, leading to a more ordered and crystalline structure.

Syndiotactic Polymer: A polymer where the substituent groups alternate sides in a regular pattern along the polymer chain, offering a balance between atactic and isotactic forms.

Crystallinity:

Refers to the degree of structural order in a polymer, where higher crystallinity typically indicates more regular arrangement of molecular chains and affects properties like strength and melting point
