## Abstract Polybutadienes (PBs) are found to form inclusion complexes with cyclodextrins (CDs) stereoselectively to give crystalline compounds in bulk. These complexes have been isolated and characterized by means of ^1^H NMR and ^13^C CP/MAS NMR spectroscopy, and Xโray diffraction. Although __ฮฑ__

Three different techniques were applied to investigate aggregation of drug/ cyclodextrin complexes, that is, drug permeation through semi-permeable membranes, determination of changes in the value of activity coefficients of drug/cyclodextrin complex solutions and transmission electron microscopy (T
