Determination of tacticity of polypropylene sulphide is studied by NMR. The measurements made by 13C-NMR are compared with those obtained by 1H 100 MHz NMR on corresponding selectively deuterated polymers. The good correlation between the two sets of results shows that stereoregularity of polypropylene sulphide can be easily found with 5 per cent precision.
