Molecular Simulation of Thermoplastic Polyurethanes under Large Tensile Deformation
TL;DR: In this paper, the mechanism of mechanical response under large tensile deformation of a common thermoplastic polyurethane comprising 4,4′-diphenylmethane diisocyanate and n-butanediol (hard segment) and poly(tetramethylene oxide) (soft segment), with atomic resolution is identified.
Atomistic Simulation of the Structure and Mechanics of a Semicrystalline Polyether
TL;DR: In this article, the authors reported the use of atomistic simulation to study semicrystalline poly(tetramethylene oxide) (PTMO), which is one of the major components of thermoplastic polyurethanes.
