| 中文摘要 | macrocyclic arylene ether ketone dimer was isolated from a mixture of cyclic oligomers obtained by the nucleophilic substitution reaction of bisphenol a and 4,4'-difluorobenzophenone and easily polymerized to high molecular weight linear poly(ether ketone). the cyclic compound was characterized by ftir, h-1- and c-13-nmr, and single-crystal x-ray diffraction. analysis of the spectral and crystal structure reveals extreme distortions of he phenyl rings attached to the isopropylidene center and of the turning points of the molecular polygons. the release of the ring strain on ring-opening combined with entropical difference between the linear polymer chain and the more rigid macrocycle at temperatures of polymerization may be the proposed motivating factors in the polymerization of this precursor to high molecular weight poly(ether ketone).
