A new lattice model of polymer crystallization is described. Results of numerical solutions of rate equations for crystallization of a two-dimensional "crystal" are presented. It is shown that the crystal thickness varies inversely with supercooling and that kinetics similar to secondary nucleation occurs. This is true even though the growth face is intrinsically rough and hence there cannot be any nucleation. The presence of a low-entropy saddle point during growth is explained, and its influence on the crystal thickness and lamellar morphology is discussed.read more

Polymer crystallization theories
TL;DR: A review of the various theories of polymer crystallization which have been proposed over the last thirty years can be found in this paper, where the authors provide guidance to the theorist in improving the models as well as to the experimentalist in interpreting his/her data.

Langevin dynamics simulations of early-stage polymer nucleation and crystallization
C. Liu,Murugappan Muthukumar +1 more
TL;DR: In this article, United-atom Langevin dynamics simulations have been performed in an effort to understand early-stage polymer crystallization at the microscopic level by following the competition between the attraction among nonbonded beads and torsional energies along chain backbones.

Formation of Chain-Folded Structures in Supercooled Polymer Melts Examined by MD Simulations
TL;DR: In this article, the first computer experiments with supercooled polymer melts of chains long enough to form chain-folded structures are reported, and the model consists of spherical beads connected by harmonic springs with an additional angle bending potential reflecting the torsional states of the underlying atomistic backbone.
