Modified Hoffman-Lauritzen theory

The growth rate kinetics of bulk semicrystalline homopolymers have been described in the past by Mandelkem et al. [1954] and Hoffman and Lauritzen [1976, 1973], using a modified version of the theory of nucleation of Turnbull and Eisher [1949] ... 

Coppola et al. [142] modified the classical nucleation theory of Hoffman and Lauritzen by adding the flow-induced increase in the Gibbs free energy of the amorphous phase to the Gibbs free energy difference between the quiescent amorphous phase and the crystalline phase. This can be expressed as follows.
