14233 IUPAC Gold Book - crystalline polymer-inclusion complex 10.1351/goldbook.14233 14233 current 1 Crystal comprising a polymer guest within a low-molar-mass host. A number of different crystalline polymer-inclusion complexes may be obtained, for example, by the crystallization of polyethylene, 1,4-polybutadiene, and other polymers within urea, perhydrotriphenylene, or cyclotriphosphazene crystals. The stems in polymer inclusion complexes are generally isolated. They are often not conformationally ordered. PAC, 2011, 83, 1831.
