A theta solvent is the name for a condition (sometimes known as the Flory condition) rather than an actual solvent. At the theta point, in the words of Paul Flory: "excluded volume interactions are neutralized." An excluded volume of zero connotes a second virial coefficient of zero. The theta state also corresponds to the highest upper critical temperature of a given polymer-solvent system.
