Rigid-rod polybenzoxazoles (PBOs) [1-3] and polyimides (PIs) [4-6] are widely used as high-performance polymers and molecular composites due to their excellent thermal stability and mechanical properties.
Polybenzoxazoles (PBOs) (7, 8) belong to a class of rigid-rod aromatic heterocyclic polymers that exhibit a high degree of orientation, high resistance to solvents, a high glass transition temperature, a high modulus, high strength, high thermal and thermooxidative stability, and low density.
