✦ Synopsis
The transition from linear polyelectrolyte to microgel polyelectrolyte is shown by a Fuoss plot of solution viscosities (Fig. 1). The ratio q s p / c falls with increasing concentration for linear polymers and for those containing lws than 0.10% divinylbenzene, and increases with increasing concentration for the swollen-sphere structures formed with O . l O ~o or more divinylbcnzene.
Current studies, to be reported soonj are directed to the effects of nucleophile structure upon reactivity with PVBC, and to the kinetic character of these displacement reactions.
