Computer simulations of supercooled polymer melts in the bulk and in confined geometry

J Baschnagel, F Varnik - Journal of Physics: Condensed Matter, 2005 - iopscience.iop.org
We survey results of computer simulations for the structure and dynamics of supercooled
polymer melts and films. Our survey is mainly concerned with features of a coarse grained …

Recent progress in flow‐induced polymer crystallization

C Nie, F Peng, R Cao, K Cui, J Sheng… - Journal of Polymer …, 2022 - Wiley Online Library
During industrial processing, such as film blowing and injection molding, semicrystalline
polymers have to be subjected to external flow. Flow changes the nucleation rate, crystal …

Equilibration of long chain polymer melts in computer simulations
