摘要: Bu calismada, poli(N-vinil kaprolaktam) mikrojellerinin sentezi ve karakterizasyonu gerceklestirilmistir. Mikrojellerin sentezi, sulu ortamda serbest radikal katilma polimerizasyonu ile emulsiyon teknigine gore yapilmistir. Farkli turde baslatici kullaniminin farkli reaksiyon sicakliklarinin etkisini belirleyebilmek amaciyla dort mikrojel sentezlenmistir. sentezinde olarak; 2,2’-azobisbutironitril (AIBN) 2,2’-azobis(2-metilpropionamid) dihidroklorur (AMPA) kullanilmistir. Mikrojeller, AIBN veya AMPA baslaticilari varliginda 70oC 80oC olmak uzere iki sicaklikta Takiben sentezlenen tum mikrojellerin verimleri belirlenmistir. Elde edilen polimerlerin yapisal analizi, Fourier Transform Infrared Spektroskopisi (FTIR) Taramali Elektron Mikroskobu (SEM) kullanilarak Ayrica urunlerin, zeta potansiyeli partikul boyutu dagilimi olcumleri Calismada elde sonuclara gore, sentez reaksiyonlari, baslaticisi sicakliginda gerceklestirildiginde en yuksek verimi edilmistir
