  "term": "Tactic block",
  "field": "Chemistry",
  "definition": "A segment within a block copolymer where all the configurational repeating units have the same tacticity. This means the stereochemical arrangement of the monomer units is consistent throughout that particular block. The presence of tactic blocks can influence the physical properties and crystallization behavior of the overall polymer.",
