A Simplified Viscometric Methodology for Rapid Experimental Screening of Polymer–Solvent Affinity

open access: yesChemistry–Methods, Volume 6, Issue 10, October 2026.
A simplified single‐point viscometric methodology enables rapid experimental ranking of polymer–solvent affinity through the hydrodynamic response of polymer chains. The approach directly estimates the Mark–Houwink parameter K, substantially reducing experimental effort while complementing conventional solvent‐screening methodologies.
