Soluble fusible propeller-type polyarylates were synthesized by single-stag
e synthesis combining polycondensation and the Diels-Alder reaction, and th
eir thermal behavior was studied. It was shown that some polarylates exhibi
t mesomorphic behavior. The resulting polymers have a molecular mass distri
bution that is rather narrow for polycondensation polymers (1.3-1.9).
