The kinetic crystallization model of Avrami is generally accepted as a starling 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 Vie Avrami index n is larger than one. These Avrami master curves have been obtained by scaling the three-parameter Avrami equation functions theta(t) with the time-values of its inflection points. In this work, alternative Avrami master curves will be displayed; they are obtained by scaling theta(t) with the mean-time (t) over bar = integral(0)(1) t d theta. These alternative Avrami master curves can be constructed for every Avrami index n > 0.
