The morphology of the intractable rigid-rod polymers is shown to be controllable by the phase separation behavior of oligomers during solution polymerization and the most important parameter to influence the phase separation behavior is the miscibility between resulting oligomers and used solvents. Perfluorinated acyloxy end group induces the liquid-liquid phase separation of oligomers and microspheres of POB having fibrillated surface are obtained. It is indicated that end groups of oligomers are also contributory to the resulting morphology.
