- A. High temperature and high pressure
- B. Low temperature and low pressure
- C. High temperature and low pressure
- D. Low temperature and high pressure
Answer
Low temperature and high pressure
Explanation
High density poly(ethene) is produced under low temperature and high pressure conditions, which allows for a more linear polymer structure.
Common mistake
Confusing Poly(ethene) Types
Students often confuse the production processes of low density and high density poly(ethene), thinking they are produced under the same conditions.
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.
