Abstract
The present work shows that sh-uctural characteristics of isotactic polypropylene fibres in terms of molecular orientation and crystallinity can be obtained with the use of X-ray diffraction, thermal analysis and infrared spectmscopy. Polarised infra-red spectra of the samples have been anelysed in detail and used for the characterisation of the orientation parameter cml. The separation of 973 cml infraced peak into 972 and 974 cml components has bean extremely useful. The peaks at 841 cml and 974 cml am used to calculate the crystalline and amorphous orientation averages, respectively.
