Abstract
A melt-processable, miscible or partially miscible blend of an amorphous, isotropic polyarylate with a poly(ether ketone ketone) that does not possess a sharp or well defined melting endotherm by differential scanning calorimetry when observed on second heating under defined conditions can be extruded into sheets useful in aircraft panels and in other applications that require high burn resistance and good melt processability.
