Model-free isoconversional method applied to polymer crystallization governed by the Hoffman-Lauritzen kinetics

A new method is developed to obtain the kinetic parameters of polymer crystallization from measure- ments of the transformation rate usually done at (but not restricted to) constant heating or cooling rates. It can be considered a generalization of the Fiedman's isoconversional method to deal w...
