Explain how low density and high density poly(ethene) can both be produced from ethene under different conditions. (Chemistry only)

In the subtopic Ceramics, polymers and composites, this learning objective focuses on explain how low density and high density poly(ethene) can both be produced from ethene under different conditions. (Chemistry only). Within Using materials, students should explain this idea in the exact curriculum context rather than as an isolated fact. Approved keywords for this objective include chemistry only, ethene, poly(ethene), and high density poly(ethene). low density poly(ethene) means a type of poly(ethene) produced under specific conditions that results in a less dense structure, making it flexible and suitable for applications like plastic bags. Avoid students often confuse the production processes of low density and high density poly(ethene), thinking they are produced under the same conditions; instead remember that low density poly(ethene) is produced at high temperatures and pressures, while high density poly(ethene) is produced at lower temperatures and pressures with a different catalyst. For exam answers, review the conditions under which low density and high density poly(ethene) are produced from ethene, focusing on temperature and pressure variations.
