Also known as tacticity, this property describes the regularity of the side group orientations on the backbone. The tacticity of a polymer has important implications for its degree of long-range order.

The side groups of isotactic polymers all have the same orientation:

Syndiotactic polymers have alternating arrangements of side-groups:

In atactic polymers the side-group orientations are random along the chain.
