    摘要: A method of impeding the evaporation of a solvent by at least partially dissolving a solvent soluble polymer in the solvent in sufficient amounts so as to impede the evaporation of the solvent is disclosed. In one embodiment the soluble polymer may be selected from the group including oligomeric or polymeric homo-, co-, and terpolymers wherein a vinylcyclohexyl moiety comprises at least 10% weight of the polymer. Another aspect is generally directed to a method of storing a solvent including placing the solvent in a suitable container for storage, and dissolving in at least a portion of the solvent sufficient amounts of a soluble polymer so as to impede the evaporation of the solvent. Also described are compositions including a solvent and a polymer dissolved in the solvent so as to impede evaporation of the solvent.
