Synthesis and spectroscopic characterization of completely isotactic   polyacrylonitrile
  Completely isotactic polyacrylonitrile (i-PAN) has been synthesized successfully by an improved urea inclusion polymerization. The tacticity of prepared samples were confirmed by 13C nuclear magnetic resonance (NMR), Fourier transform infrared (FT-IR) and X-ray diffraction (XRD).
