The dual self‐assembling polycondensation of p ‐acetoxybenzoic acid (ABA) and p ‐acetamidobenzoic acid in Therm S 800 was examined at 300 °C. Needle‐like crystals and lath‐like crystals were formed simultaneously through reaction‐induced crystallization of oligomers at a molar ratio of 30–50 mol‐% ABA in the feed. The needle‐like crystals comprised more p ‐oxybenzoyl units, whereas the lath‐like ones contained higher amounts of p ‐benzamide moieties.
