Abstract

A series of near resonance Rayleigh scattering (NRRS) experiments has been performed on the phase behavior of complex formation between polyacrylic acid (PAA) and poly(ethylene oxide) (POE). On the basis of the theory of resonance scattering, as one new method compared to resonance Rayleigh scattering (RRS), NRRS was demonstrated to investigate polymer solutions. The results indicated that the complex formation induces an increase of the intensity of resonance scattering and the phase segregation leads to distortion of the resonance scattering spectrum with decreasing pH value. The collapse of macromolecular chains is attributed to the contraction of PAA chains and association between PAA and POE. Moreover, NRRS can show more information than RRS on the basis of their scattering spectra.
