Polymer clathrate

  "id": "MLC-T-CHM-009159",
  "term": "Polymer clathrate",
  "field": "Chemistry",
  "definition": "A type of polymer co-crystal whose host is the crystalline polymer and whose guests are small molecules sitting inside molecular-sized cages or cavities, often several guests to a cavity. Because the guest need not be polymeric, a clathrate belongs to the polymer co-crystal family rather than standing apart from it. Syndiotactic polystyrene, for example, forms clathrates with small organic molecules, and removing the guest leaves a nanoporous crystal.",
