Abstract

A series of aromatic polyesters and aromatic poly( ester-amide)s have been synthesized by polycondensation of diacid chlorides containing preformed ester groups with 9,9-bis(p-hydroxyphenyl)fluorene or 9,9-bis(p-aminophenyl)fluorene, respectively. These polymers are easily soluble in polar aprotic solvents, and the polyesters are even soluble in chloroform; their solutions were cast into transparent, thin, flexible films. The polyesters are stable up to 324-335°C, while poly(ester-amide )s are stable up to 401-409°C. The dielectric constant of these polymers is in the 3.2 to 4.15 range, being lower for polyesters. All these characteristics are discussed and compared with those of related polymers without fluorene units. © 1995, Taylor & Francis Group, LLC. All rights reserved.
