WebJul 31, 2015 · At modest temperature, 280 °C, thermal decomposition of poly (styrene) proceeds smoothly to generate only styrene monomer. This arises from mainchain cleavage at a head-to-head unit present as... As a liquid or a gas, pure styrene will polymerise spontaneously to polystyrene, without the need of external initiators. This is known as autopolymerisation. At 100 °C it will autopolymerise at a rate of ~2% per hour, and more rapidly than this at higher temperatures. As the autopolymerisation reaction is exothermic it can be self-accelerating, with a real risk of a thermal runaway, potentially leading to an explosion. Examples include the 2024 explosion of the tanker Stolt Groenland, ex… WebNational Center for Biotechnology Information. 8600 Rockville Pike, Bethesda, MD, 20894 USA. Contact. Policies. FOIA.
