Photon correlation spectra of the polarized scattered light from poly (methyl methacrylate-co-4-vinylpyridine) poly (MMA-co-4VP), poly (styrene-co-styrene sulfonic acid) poly (S-co-SSA) and mixtures of both have been studied in the temperature range from 25 to 150°C. From the observed correlation functions the distribution of relaxation times is computed by means of a direct inverse Laplace transformation. The extracted L(lnτ) distributions reveal a two peak structure for poly (S-co-SSA) which exhibit a q dependence characteristic of diffusional dynamics. The mixture of the two components above 85 °C shows L(lnτ) distributions very similar to that of poly (MMA-co-4VP). We have attributed this similarity to inteipolymer complex formation via proton transfer from the SSA group to the 4VP ring and subsequent coil overlap as suggested by the NMR experiment. The observed single peak structure is dominated by the larger poly (MMA-co-4VP) and is probably the result of the screened electrostatic interactions of the SSA groups in the blend.
