Polymer Crystallization: Universal Macroscopic Description via the Autocatalytic Hoffman-Lauritzen Approach.

ABSTRACT: For the description of the crystallization in polymers, the exponential autocatalytic N ^th-order model, paired with the Hoffman-Lauritzen nucleation-growth theory (the conjunction denoted as the MCHL model), was introduced as an alternative to the classical Avrami concept. It was demonstrated, employing theoretical simulations, that the Avrami-based kinetics exhibits a strictly defined interval of asymmetries for the derivative kinetic data (conformable to the differential scanning calorimetry crystallization peaks), often incompatible with the experimental observations. On the other hand, the MCHL model is highly flexible, reproducing and largely extending the range of the Avrami asymmetries, thus effectively covering all possible single-process manifestations of the pol
