Abstract
Proton Magnetic Resonance (PMR) Imaging has been used to study the volume-phase-transition in a thermoreversible gel. This is demonstrated in the LCST polymer poly(N-isopropylacrylamide), swollen in water. The volume-phase-transition is conveniently monitored through one-dimensional proton images. PMR images, derived from relaxation and diffusion weighted planar spin-echo experiments, provide insights on the hydration state of water and the motional state of polymer, in the fully swollen and collapsed states of the gel.
