S. Yoshida et As. Hay, POLY(ARYLENE ETHER)S CONTAINING 1,5-DIBENZOYLNAPHTHALENE UNITS, Journal of macromolecular science. Pure and applied chemistry, A34(8), 1997, pp. 1299-1309
High molecular weight, soluble poly(arylene ether)s containing 1,5-dib
enzoylnaphthalene units were synthesized based on the difluorosubstitu
ted monomer derived from naphthalene and 4-fluorobenzoyl chloride by a
Friedel-Crafts reaction. The glass transition temperatures of the pol
ymers range from 199 to 259 degrees C. The 5% weight loss for these po
lymers by thermogravimetric analysis are all above 500 degrees C in ni
trogen and 480 degrees C in air.
