Abstract
Поліфенілфосфонат, що містить 4,4'-дигідроксибензофенон, синтезований як антипірен. Виявлено домішки, які можуть погіршити його властивості та термостійкість. Запропоновано очищення на основі екстракції води та гексану, внаслідок якого домішки, особливо P–Cl групи, успішно видалені без пошкодження полімеру.
A polyphenylphosphonate containing 4,4'-dihydroxybenzophenone was synthesized as a flame retardant. However, impurities were detected and may compromise its properties and thermal stability. Thus, a purification route based on water and hexane extraction with reflux was proposed. Results showed success in removing impurities, especially P–Cl groups, without damaging the polymer.
