The experimental procedures to place poly(ethylene 2,6-naphthalate) (PEN) guest molecules within gamma-cyclodextrin (gamma-CD) host molecules are described along with the subsequent verification of inclusion-compound (IC) formation. In addition, the simultaneous complexing of PEN and poly(ethylene terephthalate) (PET) with gamma-CD to form their common IC is documented. Coalescence from their common Y-CD IC generates an intimate blend of the PET and PEN polymers contained therein. Thermal analysis via differential scanning calorimetry reveals thermal behavior indicative of an intimate blend of PET and PEN. H-1 NMR analysis confirms that the intimate blending of PET and PEN achieved by coalescence from their common gamma-CD IC is not due to transesterification into a PET/PEN copolymer during thermal analysis.
