Abstract
Fluorenone polyesters made from isophthalic acid or terephthalic acid/isophthalic acid and bisphenol fluorenone have many outstanding characteristics, especially heat resistance. This paper describes the properties of several high glass transition temperature bisphenol fluorenone polyesters and copolyesters that were found to be suitable for conversion into film and fiber. In experiments, four fluorenone polyesters were characterized and their potential applications evaluated. Besides fire resistance determination, characterizations included solution viscosities, thermal analyses, dynamic mechanical analysis, and evaluation of other mechanical properties, molding, casting of films and spinning of fibers from solution, and blending with an ethylene/vinyl acetate/vinyl alcohol terpolymer (E/VA/VOH). It is shown that fluorenone polyesters have very good thermal and flame resistance and produce medium char yields in the 30-60 percent range.
