WebJan 29, 2024 · The conventional method to turn polymers into monomer is thermal decomposition. Samples of polymer can be heated to high temperature (typically 220-500 °C) to break some of the bonds that hold the monomers together [10]. When this occurs, radicals can form at the site of the broken bond, which can lead to de-polymerization [10]. WebAlex Penlidis, in Comprehensive Polymer Science and Supplements, 1989.
