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. [Pg.847]

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,... [Pg.26]
