Wide-line NMR in studies on unidirectional orientation in polymers

Polimery 1987, No 2, 41

DOI: dx.doi.org/10.14314/polimery.1987.041


The principles of interpretation of the broad-Iine-NMR spectra of unidirectionaliy oriented polymers have been discussed. The function o f orientation distribution has been introduced and presented in the form of a series o f Legendre polynomials. The possibility of calculating this function on the basis of BL-NMR spectra of deuterated polymers has been indicated. The methods of determining the coefficients of axial orientation in amorphous, completely crystalline and partially crystalline polymers on the basis of BL-NMR proton spectra have been discussed.
