A new series of bouquet-like molecules based on cyclodextrins (CD) is described. They result from the polymerization of ethylene oxide initiated by hydtoxyl groups of cyclodextrins, that constitutes the organizing core. Analysis of the structure and composition of the conjugates based on alpha-, beta- and gamma-CDs was done using C-13-NMR and data of molecular mass of conjugates. Glass transition behavior of conjugates shows that they are amorphous compounds.
