crystalline polymer-inclusion complex

https://doi.org/10.1351/goldbook.14233
Crystal comprising a polymer guest within a low-molar-mass host.
Notes:
  1. 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.
  2. The stems in polymer inclusion complexes are generally isolated. They are often not conformationally ordered.
