Abstract
The segmental relaxation of poly(acrylic acid), PAA, and poly(methacrylic acid), PMAA, in dilute methanolic solutions has been studied using time-resolved fluorescence anisotropy. The anisotropy data, as analyzed by a variety of data retrieval procedures, indicate that a single exponential function is sufficient in description of the relaxational behavior of these systems. The segmental motions of PAA and PMAA in methanol are characterized by rotational correlation times of ca. 1.3 and 4.2 ns, respectively.
