✦ Synopsis

Soluble propeller-like polyarylates with &fn 2 1 x 104 and melting in the range 200-220°C were synthesized via one-pot simultaneous Diels-Alder (using anthracene or (E,E)-I ,4-diphenylbutadiene as enophile and the fumaroyl moiety as dienophile) and polycondensation reaction. Thermal properties of all polyarylates were evaluated. Decomposition occurs in two steps between approximately 300-400 "C. The first step is due to retro-Diels-Alder reaction and the second one to main-chain decomposition.
