yes / Fluorescence spectroscopy on a series of aqueous solutions of poly(acrylic acid) containing a luminescent
label showed that polymers with molar mass, Mn < 16.5 kDa did not exhibit a pH responsive conformational
change, which is typical of higher molar mass poly(acrylic acid). Below this molar mass, polymers remained
in an extended conformation, regardless of pH. Above this molar mass, a pH-dependent conformational
change was observed. Diffusion-ordered nuclear magnetic resonance spectroscopy confirmed that low
molar mass polymers did not undergo a conformational transition, although large molar mass polymers
did exhibit pH-dependent diffusion. / Engineering and Physical Sciences Research Council (EPSRC) funded CASE award PhD. Part funded by flocculant manufacturer SNF (UK) Ltd.
