Abstract: 
Одержано фенолоформальдегідні смоли методом поліконденсації концентрованих фенолів з формальдегідом у присутності хлоридної кислоти. Концентрування фенолів проводили обробленням фенольної фракції кам’яновугільної смоли водним розчином гідроксиду натрію з наступною нейтралізацією водорозчинних фенолятів хлоридною кисло-тою. Отримано кінетичні залежності виходу смоли та температури розм’якшення від триволості процесу за 333, 353 та 373 К. Визначено порядок реакції та встановлено ефективну енергію активації даного процесу графічним методом. В інтервалі 333-373 К для реакцій поліконденсації отримано рівняння залежності виходу смоли від температури та тривалості процесу.
