  "term": "Tactic block polymer",
  "field": "Chemistry",
  "definition": "A block polymer whose chains are strung together from tactic blocks, each built from one regular configurational repeating unit, such as an isotactic block joined to a syndiotactic block. Every block is itself tactic, which separates it from a stereoblock polymer that contains an atactic block.",
