Raman spectra of various polymorphs of isotactic polypropylene
Abstract The Raman spectra of the α, γ, and smectic modifications of isotactic polypropylene (PP) are studied. The most significant spectral differences are observed in the frequency range around 2960 $ cm^{−1} $ for the spectral doublet assigned to the asymmetric stretching vibrations of the $ CH_{...

520 | |a Abstract The Raman spectra of the α, γ, and smectic modifications of isotactic polypropylene (PP) are studied. The most significant spectral differences are observed in the frequency range around 2960 $ cm^{−1} $ for the spectral doublet assigned to the asymmetric stretching vibrations of the $ CH_{3} $ groups and in the frequency range around 800 $ cm^{−1} $, which is used for analysis of the phase composition of isotactic PP. It is demonstrated that the peak positions and relative intensities of the doublet assigned to the asymmetric stretching vibrations of the $ CH_{3} $ groups can be used to identify the polymorph modifications of isotactic PP. | ||

Raman spectra of various polymorphs of isotactic polypropylene |
abstract |
Abstract The Raman spectra of the α, γ, and smectic modifications of isotactic polypropylene (PP) are studied. The most significant spectral differences are observed in the frequency range around 2960 $ cm^{−1} $ for the spectral doublet assigned to the asymmetric stretching vibrations of the $ CH_{3} $ groups and in the frequency range around 800 $ cm^{−1} $, which is used for analysis of the phase composition of isotactic PP. It is demonstrated that the peak positions and relative intensities of the doublet assigned to the asymmetric stretching vibrations of the $ CH_{3} $ groups can be used to identify the polymorph modifications of isotactic PP. © Pleiades Publishing, Ltd. 2011 |
