The kinetic crystallization model of Avrami is generally accepted as a starting point for the analysis of isothermal polymer crystallization. In a previous communication, the author has shown that data of isothermal crystallization experiments can be evaluated together with the help of Avrami master curves, if the Avrami index n is larger than one. These Avrami master curves have been obtained by scaling the three‐parameter Avrami equation functions θ( t ) with the time‐values of its inflection points. In this work, alternative Avrami master curves will be displayed; they are obtained by scaling θ( t ) with the mean‐time t̄ = ∫ 0 1t d θ. These alternative Avrami master curves can be constructed for every Avrami index n > 0.
