Popis:	Ethylene sulphide-propylene sulphide copolymers, prepared with anionic type catalysts, have been investigated by 13C NMR. The peaks have been assigned both in terms of diad and triad monomer sequences and in terms of tacticity. It has been shown that the propylene sulphide monomer units were directionally oriented and the tacticity was approximately random. We have also determined the effect of methyl substitution in various positions on the chemical shift of the main chain carbon atoms.
