Theory of solvation-induced reentrant phase separation in polymer solutions
Abstract
A simple model of solvation is introduced to describe lower critical solution points in polymer solutions. Our theory predicts that physical bond formation between polymer segments and solvents can be a major cause of miscibility gaps showing a closed-loop or hourglass shape. Relative positions of upper and lower critical solution points are examined for the various molecular weights of the polymer. The result is compared with the observed phase diagram of polyethylene glycol in water.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
