  "term": "Quality of solvent",
  "field": "Chemistry",
  "definition": "A measure of how well a solvent interacts with a polymer, influencing the polymer's conformation and solubility. A 'good' solvent promotes polymer chain expansion, while a 'poor' solvent leads to chain collapse or precipitation. This property is quantified by parameters such as the Flory-Huggins interaction parameter or virial coefficients.",
