Rezumat:

Epoxy-terminated polydimethylsiloxanes of
two molecular weights (Mn about 1,250 and 2,100) were
proved to undergo inclusion complexation into the inner
cavity of c-cyclodextrin, thus resulting in formation of
polyrotaxanes. The supramolecular assembling, the structure,
the morphology, and the thermal properties of
polyrotaxanes were shown to depend on the polymer
molecular weight, the molar ratio between the components,
and the presence of free gamma-cyclodextrin.
