Isotactic macromolecule

  "id": "MLC-T-CHM-013224",
  "term": "Isotactic macromolecule",
  "field": "Chemistry",
  "definition": "A macromolecule in which all the configurational repeating units have identical configurations at their main-chain chiral centers. This regular arrangement of substituents along the polymer backbone results in a highly ordered, stereoregular structure. Isotactic polymers often exhibit crystallinity and distinct physical properties compared to atactic or syndiotactic counterparts.",
