摘要：

Stable nitroxide radical probes are attached to styrene-divinylbenzene gel type resins through spacer arms, the length of which being 1 to 7 methylene groups. Results of electron spin resonance analysis which allows to estimate the local viscosity are discussed. Mobility of the nitroxide probes generally increases with the number of CH2 groups, the effect being compared to a decrease of cross-linking density. © 1990 Springer-Verlag.
