Stereoregularity of polyacrylonitrile determined by NMR

G. Svegliado, G. Talamini, G. Vidotto

Abstract

Abstract The NMR spectrum of polyacrylonitrile is interpreted and the tacticity of three polyacrylonitrile samples prepared at different temperatures in the range from −78 to 120°C. determined. The ratio between isotactic and syndiotactic units is about 50:50 for all the three samples examined.
