摘要：

The orientation of 9,10-di-n-alkylanthracene probes dissolved in cis-1,4-polyisoprene networks was determined at different degrees of network extension. Orientation measurements were carried out by the fluorescence polarization method. The orientation of network chains containing anthracene groups was determined independently. Results of the measurements show that the n-alkyl probes are orientationally coupled to network chains. The degree of coupling increases linearly with the length of the probe chain and is independent of the extension ratio over a wide range.
