Finemann-Ross equation

Because the instantaneous composition of the copolymer is directly inaccessible, the conversion must be limited to 5% for the composition of the mixture of comonomers to remain sensibly equal to the initial one. To utilize the Finemann-Ross equation, one has to plot G against F for various experimental values, where the slope of the resulting line corresponds to n while the intercept with the ordinate corresponds to r. ... 

Although frequently used, the Finemann-Ross method is not accurate for low values of [A]/[B] (or [B]/[A]) and is not suitable for a wide range of concentrations. The method described by Kelen and Tiidos is often preferred it consists of dividing all the terms of the Finemann-Ross equation by (a + F), with the value of the constant a being taken equal to (Fmin/ max) ...
