The salts\u2019 effects on phase separation are found to correlate with the change in the entropy related to the structural changes in water during anion hydration. The same salts\u2019 effects on phase separation in aqueous solutions of branched PEG and polyvinylpyrrolidone at a polymer concentration of 10 wt.% were also examined. The results obtained support the assumption that phase separation in aqueous polymer\u2013salt systems is an entropy-driven process.<\/jats:p>","DOI":"10.3390\/ijms26104545","type":"journal-article","created":{"date-parts":[[2025,5,9]],"date-time":"2025-05-09T08:20:23Z","timestamp":1746778823000},"page":"4545","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Effects of Inorganic Salts on Phase Separation in Aqueous Solutions of Poly(ethylene glycol)"],"prefix":"10.3390","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6886-7119","authenticated-orcid":false,"given":"Pedro P.","family":"Madeira","sequence":"first","affiliation":[{"name":"BiotecFoz, 4250-242 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4037-5857","authenticated-orcid":false,"given":"Vladimir N.","family":"Uversky","sequence":"additional","affiliation":[{"name":"Department of Molecular Medicine and Byrd Alzheimer\u2019s Research Institute, Morsani College of Medicine, University of South Florida, Tampa, FL 33612, USA"}]},{"given":"Boris Y.","family":"Zaslavsky","sequence":"additional","affiliation":[{"name":"Cleveland Diagnostics, 3615 Superior Ave., Cleveland, OH 44114, USA"}]}],"member":"1968","published-online":{"date-parts":[[2025,5,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Titus, A.R., Madeira, P.P., Uversky, V.N., and Zaslavsky, B.Y.
