Abstract

The orientational order generated in a polymer network by an uniaxial stress is probed with NMR. The experiments are performed on an end-linked polydimethylsiloxane network. When a uniaxial force is applied a detailed analysis of the spectrum shows that the segmental motions become uniaxial around constraint direction. This experimental fact is explained by shortrange orientational interactions between chain segments.
