SPECTROSCOPIC CRITERION OF THE ISOTACTICITY OF POLYPROPYLENE
Y u . V. K i s s i n , G. P. B e l o v , I. V. E r e m i n a . E. A. V e l i c h e n k o v a , V. I. T s v e t k o v a a n d N. M. C h i r k o v , V y s o k o m o l . s o y e d . 5: No. 7, 1117, 1963. AN A N A L Y S I S of the I R and X-ray spectra of liquid polypropylene specimer~s obtaine(t with the aid of a TiCI4-AI(C2Hs),C] catalyst led to the conclusion that the intensity of the 1154 and 976 cm --~ I R ban(is is a criterion of the isotacticity of this polymer. The bands are absent in spectra of atactic polypropylene and are present in isotactic specimens.
