KUCHSIZ ASOSLI ANIONITNING NOIZOTERMIK PARCHALANISHI KINETIK VA TERMODINAMIK TAHLILI
##submission.downloads##
Akrilonitrilning divinilbenzol bilan sopolimeri asosidagi amidin guruhli kuchsiz asosli anion almashinuvchining termik tahlili o‘tkazildi. Ikki parchalanish oralig‘i aniqlandi: I (26,39-278,63°C) – labil bo’laklarni suvsizlantirish va destruksiyasi (Ea ≈ 55 kJ/ mol), II (278,63-600,89°C) – polimer zanjiri va funktsional guruhlarning destruksiyasi (Ea≈180 kJ/mol). Termodinamik parametrlar hisoblab chiqilgan. Materialning 400°C gacha chidamliligi va yuqoria haroratlarda ishlatilish mumkinligi aniqlangan.
