Huggins equation - Wikipedia

WebThe Huggins Equation is an empirical equation used to relate the reduced viscosity of a dilute polymer solution to the concentration of the polymer in solution. It is named after Maurice L.

The equation was first proposed in 1950 by Paul J. Flory and Thomas G. Fox while at Cornell University. Their work … See more The Flory–Fox equation relates the number-average molecular weight, Mn, to the glass transition temperature, Tg, as shown below: $${\displaystyle T_{g}=T_{g,\infty }-{\frac {K}{M_{n}}}}$$ See more The Flory–Fox equation serves the purpose of providing a model for how glass transition temperature changes over a given molecular weight range. Another method to modify the glass transition temperature is to add a small amount of low molecular weight See more bmo harris bank germantown
