Abstract
A new tetraphenylated heterocyclic diol, 2,5-bis(4-hydroxyphenyl)-3,4-diphenylthiophene, was synthesized in three steps starting from 4-methoxydeoxybenzoin. The tetraphenylthiophene-containing polyarylates having inherent viscosities of 0.29—0.84 dlg−1 were prepared by the high temperature solution polycondensation of the diol with various aromatic dicarboxylic acid chlorides. All the polyarylates were crystalline or semicrystalline, and the crystalline polyarylates were quite insoluble in organic solvents, while the others dissolved readily in a variety of solvents including N-methyl-2-pyrrolidone and sym-tetrachloroethane. These polymers had glass transition temperatures in the range of 209—260°C, with no weight loss below 400°C in both air and nitrogen atmospheres.
