Can ethene be polymerised
WebDuring the polymerisation of ethene, thousands of ethene molecules join together to make poly (ethene) - commonly called polythene. Ethene is known as the monomer. Poly … WebJul 31, 2024 · The initiation step involves formation of radicals, and chain propagation entails stepwise addition of radicals to ethene molecules. Chain termination can occur by any reaction resulting in combination or disproportionation of free radicals. The polyethene produced in this way has from 100 to 1000 ethene units in the hydrocarbon chain.
