Polymer Degradation and Stability
Abstract
Abstract 2-Tert-butyl-6-(3-tert-butyl-2-hydroxy-5-methylbenzyl)-4-methylphenyl acrylate (Sumilizer GM) is shown to be a very effective stabiliser for thermal degradation of butadiene type polymers under an oxygen-free atmosphere. The stabilising mechanism is confirmed to be a unique bifunctional mechanism, which consists of polymer radical trapping by the acrylate group, followed by fast hydrogen transfer from intramolecular hydrogen-bonded phenolic hydroxyl groups to result in stable phenoxyl radicals.
