Summary
Proton relaxation time measurements of chemical crosslinked polystyrenes swollen in protonated and deuterated benzene have been done in order to get informations on the microdynamic behaviour of polystyrene as well as of benzene molecules under the influence of the polymeric network. By means of additional T1d-measurements further evidences for a slow anisotropic motion could be obtained, which cause a T2-“plateau” in the high temperature region. The results are compared with those of MAR-experiments.
