摘要：

An analysis of the structure of the mesomorphic form of syndiotactic polystyrene (s-PS), through Fourier transform calculations on models constituted by large bundles of chains, is presented. Further information on the structural organization in the mesomorphic form is also provided by Fourier transform infrared (FTIR) spectra, in the frequency regions for which well-defined differences exist between the spectra of samples in the alpha and beta crystalline forms. Both theoretical and experimental data provide support for the hypothesis that the mesomorphic form of s-PS contains small and imperfect crystals of the a crystalline form.
