## Abstract Two new polyimides (ODA‐PI and HDA‐PI) having 1,4‐phenylenediethynylene unit and octyloxy groups were synthesized. Judging from inherent viscosities of their precursor PAAs (1.42 and 1.62 dL · g^βˆ’1^), the two PIs were very high in molecular weight. Casting and thermal imidization of PAA
