Tacticity - Stereoisomerism | ||||||||
It indicates when they are linked to each other in the same way (for example, from head to tail), but they differ in their spatial arrangement, this really focuses on the 3D arrangement of the groups of side chains. Three most prevalent configurations:
| ||||||||
Isotactic polymers | ||||||||
All R groups are on the same side of the chain. | ||||||||
Syndiotactic polymers | ||||||||
Alternating sides of the chain. | ||||||||
Atactic polymers | ||||||||
The R groups are "random" | ||||||||
