Recycling Behavior of Thermoreversibly Diels–alder Crosslinked Epm

Abstract

The recyclability of thermoreversibly Diels–Alder (DA) crosslinked EPM has been studied. The retro DA reaction dominates over the dehydration–aromatization process of the DA adduct. Moreover, a negative influence of air occurred as a result of a crosslinking in air flow. Nevertheless, rubber compounds prepared from EPM-g-furan and carbon black can be recycled several times without losing mechanical strength, a feature attributed to a strong antioxidant effect of the carbon black.

Rapid self-healing in IR-responsive plasmonic indium tin oxide/polyketone nanocomposites

“…7 The exceptional properties of smart materials enable their application in elds like drug delivery, 8 oil recovery, 9 sensors, 10 so actuators, 11 energy harvesting, 12,13 and self-healing materials. 14 Nowadays, sustainability is a crucial societal topic, especially in terms of polymer material pollution. A wise solution to this issue is found in the design of self-healing polymers.…”

Recyclability of Photoinduced Cross-Linked EPM Rubber with Anthracene-Grafted Groups: Problems and Their Solutions

“…Recently a reversible Diels–Alder (DA) reaction has been applied for thermoreversibly cross-linked rubber and thermosets . Nevertheless, some irreversible cross-linking reactions may take place under the same experimental conditions (high temperature) in which the de-cross-linking retro-DA reaction occurs . Moreover, for some manufacturing protocols, e.g., three-dimensional (3D) printing, photoinduced cross-linking is more preferable.…”
