With the study, The aim is increase thermal stability of copolymer derivatives.For this purpose, maleic anhydride-vinyl acetate (MAVA) copolymers; monoesters and carboxylate salt derivatives of its were obtained by reaction of maleic anhydride vinyl acetate copolymer with n-propyl alcohol, n-butyl alcohol and ammonia. Structural characterization of these derivatives was carried out by Fourier transform infrared spectroscopy (FTIR) and Thermogravimetric Analysis (TGA) was used at thermal analysis. In conclusion according to the TGA curve as compared to the heat stability and were found to be the most stable of the carboxylate derivatives of the ester derivatives of the least stable
Özet. Yapılan çalışma ile kopolimer türevlerinin ısısal kararlılığını artırmak amaçlanmıştır. Bu amaçla maleik anhidrit-vinil asetat (MAVA) kopolimeri n-propil alkol, n-butil alkol ve amonyak ile tepkimeye sokularak onun monoester ve karboksilat tuzu türevleri elde edildi. Bu türevlerin yapısal karakterizasyonu Fourier dönüşümlü infrared spektroskopisi (FTIR) ile yapılırken ısısal analizlerde Termogravimetrik Analiz (TGA) kullanıldı. Araştırma sonucunda TGA eğrilerine göre ısıya karşı kararlılıkları karşılaştırıldığında karboksilat türevlerinin en kararlı olduğu ve en az kararlı olanın ise ester türevlerinin olduğu görülmüştür.
