Abstract

Some properties of polydimethylsiloxane (PDMS) polymer networks, which have been put into evidence by use of Deuterium Nuclear Magnetic Resonance (2H NMR), will be described in this paper. The anisotropy of molecular motions (in the time range 10−6 to 10−5s) may be investigated with this technique. It has been already shown that deuteriated probes(solvent or free PDMS chains)dissolved in uniaxially deformed networks, acquire a uniaxial orientational order, which means that their motions, in the range 10−5s, become uniaxial around the applied force direction 1–3. This property and specifically the free chain orientation has been interpreted as the effect of orientational interactions between chain segments.
