Fourier transform infrared (FTIR) spectra of syndiotactic polystyrene (s-PS) semicrystalline samples have been examined by using the spectral subtraction approach. For the crystalline forms including trans-planar chains (trigonal a and orthorhombic b) a number of conformational and structural order
## Abstract Several syndiotactic polystyrene (sPS) samples have been synthesized by using different catalytic systems. Their stereochemistry has been determined by ^13^C NMR spectra in both the aliphatic CH~2~ and aromatic C~1~ resonance regions. The observed peaks have been unambiguously assigned
