By now, sufficient information on the dynamics of macroinolecules in solution has bci ii accumulated by means of dynamic light scattering, this method being sensitive to the internal modes of a macromolecule s motion and to the process of its reptation among similar molcondensed state. At the same time, there is a lack of unambiguous evidence for association mode s" or the lifetime of as.sociates in the voluminous literature on dynamic light scattering from polymer solutions.

One additional item of experimental evidence for the dimeric association of polyisoprenyl lithium was provided by a light scattering study (21), in n-hexane at 25°C., where it was found that the molecular weight of the terminated polymer was very close to one-half that of the active polymer. All of these data seem to leave no doubt that the active chain ends in the organo-lithium polymerization of styrene, isoprene and butadiene, in non-polar solvents, are associated as pairs, at least at chain-end concentrations of 10 2 M or less. This conclusion has also been supported by data obtained in four other laboratories (22,...
