Bu çalışmada (2-hidroksi-3-benzofenoksipropil metakrilat0.45 - benzil metakrilat) kopolimerinin

ters 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 enjekte

edilerek probların spesifik alıkonma hacimleri (

o

g V ) tayin edildi. Camsı geçiş sıcaklığı Tg’ yi tayin

etmek için (1/T; ln

o

g V ) grafikleri çizildi. Her iki grafikten de P(HBFPMA0.45-ko-BMA)’ nin camsı

geçiş sıcaklığı 98 oC olarak bulundu. Tg’nin altındaki sıcaklıklarda adsorpsiyon ısısı Ha ve Tg’nin

üzerindeki sıcaklıklarda sorpsiyona ait G1

s, H1

s ve S1

s değerleri hesaplandı. Sonsuz seyreltik

hal için polimer-çözücü etkileşimleri

 1 ,



12  , G1

 ve H1

 değerleri ve aynı sıcaklık

aralığında kopolimerin çözünürlük parametreleri (2) bulundu. P(HBFPMA0.45-ko-BMA)’nin

çözünürlük parametreleri (2) sıcaklık arttıkça azaldı. Bulunan sonuçlar kullanılan probların

kopolimer için zayıf çözücü olduğunu gösterdi.
