Abstract

In this work, The thermodynamic properties of (2-hydroxy-3-benzophenoxypropyl methacrylate0.45-benzyl methacrylate) copolymer were investigated by inverse gas chromatography (IGC) for polymer-probe systems. A series of alkanes and alcohols were used as probes at different temperatures.The specific retention probe volumes ( o gV ) of probes were determined by injecting each probe into the colon. The glass transition temperatures were determined by the plot of ln ( o gV ) againts 1/T. In both graphs, the glass transition temperature of P(HBFPMA0.45-ko-BMA)was found to be 98 oC. The adsorption temperature Ha at temperatures below Tg and G1s, H1s and S1s of the sorption at temperatures above Tg were calculated. The polymer-solvent interactions  1 ,  12  , G1 and H1 for the infinite diluted state and the solubility parameters () of the copolymer at the same temperature range were found. The solubility parameters () of P(HBFPMA0.45-ko-BMA) decreased as the temperature increased. These results showed that the probes used were poor solvents for the copolymer.

Özet

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 gV ) tayin edildi. Camsı geçiş sıcaklığı Tg’ yi tayin etmek için (1/T; ln o gV ) 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 G1s, H1s ve S1s 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.
