WebAug 25, 2024 · n CH 2 =CH 2 → [ CH 2 CH 2 ] n. During the polymeriation of ethene, thousands of ethene molecules join together to make poly (ethene) - commonly called polythene. The reaction is done at high pressures in the presence of a trace of oxygen as an initiator. Some common addition polymers are listed in Table 27.8.1. WebThe products of reaction are ethylene oxide, and carbon dioxide and water. There appear to be two processes whereby the carbon dioxide is formed: (1) by direct oxidation of the ethylene not via ethylene oxide, and (2) by the further oxidation of the ethylene oxide.
