Abstract: In order to take oligomers as the model compounds to study the microstructure of PEDEK, two linear oligomers with different chain ends were synthesized.Their properties have been investigated by means of MS, 1HNMR, ICP, IR, DSCand WAXD.The hydroxy-ended oligomer Adue to its intermolecular hydrogen bond has very similar X-ray diffractions to the polymer, while oligomer B′s diffractions are much different from those of the polymer.
