Covalent bond scission in the Mullins effect of a filled elastomer: real-time visualization with mechanoluminescence
TL;DR: In this article, light emission from mechanoluminescent cross-linkers in silica-filled poly(dimethylsiloxane) was studied and shown to contribute significantly to irreversible stress softening upon the initial extension, known as the Mullins effect.

Thermoplastic polyurethanes derived from petrochemical or renewable resources: A comprehensive review
Janusz Datta,Paulina Kasprzyk +1 more
TL;DR: A review of the synthesis and the structure-properties relationship analysis in the case of thermoplastic polyurethanes (TPUs) is presented in this paper. But the most popular reactants used for the production of the TPUs have petrochemical-based origin.
