Abstract

Çözelti polimerizasyonu yöntemiyle sentezlenen Morfolino etil metakrilamid polimerinin (PMoEMA), camsı geçiş sıcaklığının (Tg) üstündeki sıcaklıklarda termodinamik özellikleri Ters Gaz Kromatografisi (TGK) yöntemiyle incelenmiştir. Bu amaçla, aromatik hidrokarbonlar ve alkollerin sorpsiyonuna ait termodinamik parametreler (kısmi molar entalpi, kısmi molar serbest enerji, ve kısmi molar entropi), ağırlık kesri aktiflik katsayıları, Flory-Huggins etkileşim parametreleri ve polimer ile çözücü için çözünürlük parametreleri hesaplanmıştır.
