Factors Affecting the Size of Aqueous Poly(vinylphenol-co-potassium styrenesulfonate)/Poly(ethylene oxide) Complexes

The diffusion properties of complexes formed between poly(ethylene oxide) (PEO) and poly(vinylphenol-co-styrenesulfonate) (PKS) in aqueous medium were investigated by diffusion ordered NMR (DOSY), fluorescence photobleaching recovery (FPR), and viscosity measurements. All three techniques showed that PEO/PKS complexes range from single PEO coils with bound PKS molecules to large complex species containing many PEO chains. For a given PKS …
