Tacticity

Tacticity refers to the arrangement of the polymer chains' repeating structural units in relation to one another, particularly in stereochemistry. It is a key concept in polymer science and chemistry that affects the physical properties of polymers. There are three main types of tacticity: 1. **Isotactic**: In isotactic polymers, all the substituent groups (or side chains) are on the same side of the polymer chain, leading to a regular and symmetrical structure.
