Maleik Anhidrit Vinil Asetat Kopolimerinin Ester ve Karboksilat Tuz Türevlerinin Sentezi ve Karakterizasyonu

Ozet.  Yapilan calisma ile kopolimer turevlerinin isisal kararliligini artirmak amaclanmistir. Bu amacla maleik anhidrit-vinil asetat (MAVA) kopolimeri n-propil alkol, n-butil alkol ve amonyak ile tepkimeye sokularak onun monoester ve karboksilat tuzu turevleri elde edildi. Bu turevlerin yapisal karakterizasyonu Fourier donusumlu infrared spektroskopisi (FTIR) ile yapilirken isisal analizlerde Termogravimetrik Analiz (TGA) kullanildi. Arastirma sonucunda TGA egrilerine gore isiya karsi kararliliklari karsilastirildiginda karboksilat turevlerinin en kararli oldugu ve en az kararli olanin ise ester turevlerinin oldugu gorulmustur. Abstract.  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.
