摘要：

Nucleophilic polycondensation at high concentration between benzene-1,3-dithiol and 4,4'-difluorobenzophenone affords not only linear polymer 1 but also a significant yield (ca. 8%) of cyclic oligomers, mainly the [2+2] cyclodimer 2. Under high-dilution conditions 2 becomes by far the major reaction product. Macrocycle 2 has been isolated, structurally characterised by single-crystal X-ray methods and found to undergo rapid anionic ring-opening polymerisation in the melt (330-360 degrees C), affording a linear, high molecular weight poly(arylthioether ketone).
