At 25 degrees C mainly solid-liquid phase separations took place. On the other hand, at 50 degrees C, liquid-liquid phase separations were observed, Thus, it was possible to fractionate PPO on the basis of molecular weight. From the molecular weight measurements, it was concluded that 1 molecule of high PPO was formed for less than 10 Fe atoms.eninfo:eu-repo/semantics/closedAccess[No Keyword]Article352317325WOS:A1996UC032000082-s2.0-0030106732N/AN/A
