In polymer chemistry and polymer physics, the Flory–Fox equation is a simple empirical formula that relates molecular weight to the glass transition temperature of a polymer system. 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
