Abstract

Poly(ε‐caprolactone) was found to form inclusion complexes with α‐cyclodextrin to give crystalline compounds. The complexes are stoichiometric one‐to‐one (cyclodextrin: monomer unit) compounds. The yields of the complexes decreased with increasing the molecular weight of the polymer. They were characterized by IR, ^1^H NMR, ^13^C CP/MAS NMR, and X‐ray diffraction. The inclusion modes are discussed.
