WebMay 17, 2024 · Theta Symbol meaning . Unlike other icons, this one combines the functions of a letter and a symbol. Theta is the eighth letter from the Greek alphabet. It is used in … 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, the theta condition is satisfied at a certain temperature, called the theta (θ) temperature or theta point. A solvent at this temperature is … 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 WebFeb 21, 2024 · The \(\Theta\) temperature corresponds to the spinodal temperature of the VPT at which the polymer behaves like an ideal chain and the Flory parameter becomes \(\chi _1=1/2\).
