Question
How does the polymerization condition affect the density of poly(ethene)?
Answer
The density of poly(ethene) is affected by the polymerization conditions; low density poly(ethene) is produced under high temperatures and pressures, while high density poly(ethene) is made at lower temperatures and pressures.
Explanation
This answer is strong as it explains the specific conditions that lead to different densities in poly(ethene), directly linking to the learning objective about how conditions influence polymer properties. It tests the student's ability to apply their knowledge to specific examples.
Common mistake
Misunderstanding Polymer Properties
Students often think that all polymers have the same properties regardless of their monomers and production conditions.
Emphasize that polymer properties vary significantly based on the specific monomers used and the conditions under which they are synthesized.
