Abstract
New biphenyl-2,2′-diyl and 1,1′-binaphthyl-2,2′-diyl-containing polyarylates having inherent viscosities up to 1.02 dl g−1 were synthesized by the phase-transfer catalyzed two-phase polycondensation from the diacid chlorides of 2,2′-bis(p-carboxyphenoxy)biphenyl or 2,2′-bis(p-carboxyphenoxy)-1,1′-binaphthyl and various bisphenols. These polyarylates were readily soluble in a variety of organic solvents including N-methyl-2-pyrrolidone, m-cresol, pyridine, and chloroform. These polymers containing biphenyl and binaphthyl units had glass transition temperatures in the range of 144—200°C and 215—268°C, respectively. They began to lose weight at around 400°C, with 10% weight loss being recorded at about 450°C in air. © 1994 The Society of Polymer Science, Japan. All rights reserved.
