Bu çalışmada, Maleik anhidrit/Stiren (MAS) kopolimeri sentezlendi. Sentezlenen kopolimer karakterize edildi ve iki farklı primer alkol (propil ve bütil) ile modifiye edildi. Kopolimer ve iki modifiye türevinin çözünme, FT-IR ve termomekanik (TMA) analizleri gerçekleştirildi. Türevlerin ester sayıları hesaplandı. Alkoller ile modifiye edilen türevler MAS kopolimeri ile aynı çözünme davranışları gösterdiyse de, daha hızlı çözündükleri saptandı. Modifikasyon işlemi FT-IR ile doğrulandı. Ester türevlerinin MAS kopolimerine göre daha elastik ve düşük camsı geçiş sıcaklığına sahip olduğu görüldü. Türevlerin ester sayılarının birbirlerine yakın olduğu hesaplandı.
In this study, Maleic anhydride/Styrene (MAS) copolymer was synthesized. The synthesized copolymer was characterized and then modified with two different primary alcohols (propyl and butyl). Dissolution, FT-IR and thermo-mechanical (TMA) analyzes of the copolymer and its two modified ester derivatives were performed. The ester numbers of the obtained derivatives were calculated. Although the ester derivatives showed dissolution behavior in the same solvents as the MAS copolymer, they dissolved faster. Modification was confirmed in the FT-IR spectra. It was also found that the derivatives were more elastic than the MAS copolymer and had a lower glass transition temperatures. The calculated ester numbers were also close to each other.
