In solution polymerized samples of poly(p-oxybenzoate), the fraction of phase II and resultant morphology is affected by polymerization temperature, time, and concentration. The two phases have approximately the same crystal-mesomorph transition temperature (Tk-m) and their morphology cannot be distinguished. Phase II appears to contribute to the coherence of the discs and whisker-discs found for certain solution polymerization conditions. The relationship of the morphology to Tk-m is discussed.
