摘要：

Using a stopped-flow apparatus with fluorescence detection we followed the expansion of poly(methacrylic acid) after a pH jump, the enhancement of fluorescence of Auramine O after association with poly(methacrylic acid), the counterion exchange in ionomer solutions and the dependence of the rate of inter-polymer reactions on the polymer chainlength. Fluorescence was also used to follow the unfolding of collapsed chains in bulk polymers and counterion diffusion in bulk ionomers.
