14239 IUPAC Gold Book - polymer clathrate 10.1351/goldbook.14239 14239 current 1 Polymer co-crystal in which low-molar-mass guest species are hosted in molecular-sized cages or cavities containing more than one guest molecule. Polymer clathrates are formed by many polymers with low-molar-mass compounds, particularly water. Examples are frequent among biological polymers (e.g., amylose) but also some synthetic polymers give polymer clathrates (e.g., poly(ethylene oxide) with various inorganic and organic species). Guest molecules are often packed isolated from each other or in columns. Polymer co-crystal https://goldbook.iupac.org//terms/view/14240 PAC, 2011, 83, 1831.
