Abstract: Abstract T1ρH′ the proton spin‐lattice relaxation time in the rotating frame, can be used as a probe for polymer blend miscibility in the same way the glass transition temperature (Tg) is used. T1ρH has some advantages over Tg. It is indicative of the separate phases at a level of a few nanometers, below what Tg can distinguish. Also, T1ρH is the only parameter related to the local proton density in a sample. This paper shows a few examples of T1ρH investigations, including thermally reversible blends, phase …
