Abstract: 
fiogf49gjkf0d

New polyarylates were synthesized by phase‑transfer catalyzed two‑phase polycondensation of benzofuro[2,3‑b]benzofuran 2,9‑dicarbonyl chloride with bisphenols of various derivatives and 2,13‑dihydroxy[7a,14c]dihydronaphtho-[2,1‑b] naphtho[1´,2´:4,5]furo[3,2‑d] furan with various aromatic dicarboxylic acid chlorides. All of these polyarylates dissolve readily in a wide range of organic solvents such as N,N´-dimethylacetamide, N-N´-dimethylformamide, and hexamethyl phosphoramide. These polyarylates have inherent viscosities of 0.14–0.30 dL/g and 10% weight loss between 302.9–455.8 °C in nitrogen atmosphere
