The quality of the solvent depends on both the chemical compositions of the polymer and solvent molecules and the solution temperature. Theta temperature. If a solvent is precisely poor enough to cancel the effects of excluded volume expansion, the theta (θ) condition is satisfied. For a given polymer-solvent pair, … See more In a polymer solution, a theta solvent (or θ solvent) is a solvent in which polymer coils act like ideal chains, assuming exactly their random walk coil dimensions. Therefore, the Mark–Houwink equation exponent is See more • Flory–Huggins solution theory See more The conformation assumed by a polymer chain in dilute solution can be modeled as a random walk of monomer subunits using a See more Thermodynamically, the excess chemical potential of mixing between a theta solvent and a polymer is zero. Equivalently, the enthalpy of mixing is zero, making the solution See more
