Abstract

Bu çalışmada poli (2-floranilin), poli (2-kloranilin) ve poli (2-iyotanilin), tetrabutilamonyum persülfat yükseltgen maddesi kullanılarak asidik ortamda kimyasal yöntemle sentezlenmiştir. Ayrıca anilinin, 2-haloanilinler ile aynı ortamda kopolimerizasyonu gerçekleştirilmiştir. Polimerlerin hazırlanmasında yükseltgen olarak kullanılacak tetrabutilamonyum persülfat (TBAP), tetrabutilamonyum hidroksit ve potasyum peroksidisülfatın reaksiyonu sonucunda elde edilmiştir. Polimer ve kopolimerlerin karakterizasyonu elemental analiz, FTIR ve UV-Vis spektroskopisi yöntemleri ile gerçekleştirilmiştir. Kopolimerlerin elektriksel iletkenliğinin poli(2-halojenanilin)lerden daha yüksek, polianilinden ise daha düşük olduğu gözlenmiştir. Kopolimerlerin iletkenliğinin polianilinden daha düşük olması, polianilin zincirine halojen atomlarının katılmasının bir sonucudur. Sentezlenen polimer ve kopolimerlerin çeşitli organik çözücülerdeki çözünürlükleri tayin edilmiştir.
