AB  - Bu çalışmada (2-hidroksi-3-benzofenoksipropil metakrilat0.45 - benzil metakrilat) kopolimerininters gaz kromatografisi (IGC) ile polimer-prob sistemleri için termodinamik özellikleri incelendi.Farklı sıcaklıklarda prob olarak bir seri alkan ve alkol kullanıldı. Her bir prob kolona enjekteedilerek probların spesifik alıkonma hacimleri (og V ) tayin edildi. Camsı geçiş sıcaklığı Tg’ yi tayinetmek için (1/T; lnog V ) grafikleri çizildi. Her iki grafikten de P(HBFPMA0.45-ko-BMA)’ nin camsıgeçiş sıcaklığı 98 oC olarak bulundu. Tg’nin altındaki sıcaklıklarda adsorpsiyon ısısı Ha ve Tg’ninüzerindeki sıcaklıklarda sorpsiyona ait G1s, H1s ve S1s değerleri hesaplandı. Sonsuz seyreltikhal için polimer-çözücü etkileşimleri 1 ,12  , G1 ve H1 değerleri ve aynı sıcaklıkaralığında kopolimerin çözünürlük parametreleri (2) bulundu. P(HBFPMA0.45-ko-BMA)’ninçözünürlük parametreleri (2) sıcaklık arttıkça azaldı. Bulunan sonuçlar kullanılan problarınkopolimer için zayıf çözücü olduğunu gösterdi.
