A tactic macromolecule, essentially comprising only one species of configurational base unit, which has chiral or prochiral atoms in the main chain (backbone) in a unique arrangement with respect to its adjacent constitutional units.
Notes: - In an isotactic macromolecule, the @C01253@ is identical with the configurational base unit.
- An isotactic macromolecule consists of @M03856@.
