โœฆ Synopsis

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 between two subsequent double bonds. An analogous dependence was observed, in the copolymers studied, on the ethylene-propylene ratio. It is pointed out that it is more suitable, in the study of polymers, to examine a series of comparable samples than to study separately a single polymer.
