摘要：

Pulsed-field gradient NMR has been used to study the self-diffusion of polyions and counterions in polyelectrolyte solutions. The concentration dependence indicates a transition between the concentrated and semidilute regimes. In both regimes the molecular weight dependence is approximately M-1 and mixtures of different molecular weights show an interesting behaviour. Mixtures with M(omega)/M(n) < 1.3 behave as a single fraction.
