Abstract

Nylon3 was prepared through base-catalayzed hydrogen transfer polymerization of acrylamide. The polymer was fully characterized by FTIR, FT-Raman, 1H-NMR, 13C-NMR, DSC, TGA, XRD, MALDI-MS, and end-group analyses. Glass transition temperature, thermal degradation temperature, d-space values, crystallinity, average molecular weights and polydispersity of nylon3 obtained were determined. Initiation, propagation and termination mechanisms of base-catalyzed hydrogen transfer polymerization of acrylamide were proposed using the structural analyses of nylon3 obtained.

Abstract

N aylon3 akrilamitin baz katalizli hidrojen transfer polimerizasyonu ile hazırlandı. Polimer FTIR, FT-Raman, 1H-NMR, 13C-NMR, DSC, TGA, XRD, MALDI-MS ve uç grup analizleri ile tamamen karakterize edildi. Camsı geçiş sıcaklığı, termal bozunma sıcaklığı, kristal yüzdesi, d-boşluk değerleri, ortalama molekül kütlesi ve polidispersitesi belirlendi. Akrilamitin hidrojen transfer polimerizasyonunun başlama, büyüme ve sonlanma basamakları elde edilen naylon3 polimerinin yapısal analizi kullanılarak önerildi
