Abstract
A method for evaluating the pentad tacticity of polyacrylonitrile (PAN) was proposed by analyzing the splittings of the CN carbon NMR peak with high magnetic field 13C NMR. The method was applied to PAN prepared by polymerization with a redox catalyst (R-PAN). The results showed that R-PAN is completely random in stereoregularity and the peak assignment for CN and CH carbons of R-PAN, formerly carried out for evaluating the triad tacticity, was confirmed as correct.
