This paper is devoted to a comparative study, performed by means of NMR, of properties and behaviour of an homologous series of polyalkenamers and of some ethylene-propylene copolymers. It was observed that, in polyalkenamers, the chain mobility depends on the number of methylene groups present betw
Ethylene sulphide-propylene sulphide copolymers, prepared with anionic type catalysts, have been investigated by t3C 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 directi
