Abstract
Polyarylenes prep. by either 1) polycondensing with dehydrogenation of partially hydrogenated aromatic cpds. using a catalyst at >=400 degrees C and >=42 kg/cm2 in presence of H2, or 2) reacting aromatic cpds. at a mixture of aromatic and partially hydrogenated aromatic cpds. with a catalyst of 200-700 degrees C at 42-140 kg/cm2 in presence of H2. Combine good high temperature stability with good solubility and fusibility, and are free of chloride and other impurities.
