An isotactic macromolecule consists of 100% meso diads. Polypropylene formed by Ziegler–Natta catalysis is an isotactic polymer. Isotactic polymers are usually semicrystalline and often form a helix configuration.

What is the meaning of isotactic?

: having or relating to a stereochemical regularity of structure in the repeating units of a polymer — compare atactic.

What is isotactic polymer with example?

An isotactic polymer is a polymer which has the substituents on the same side of the carbon chain. That means; all the substituents of the polymer material are located on the same side of the backbone of the polymer. For example, industrially prepared polypropylene is isotactic.
