Question
Explain how a thermosoftening polymer behaves differently from a thermosetting polymer when heated, and give one example of each type of polymer.
Answer
A thermosoftening polymer softens and can be reshaped when heated, but returns to its original shape when cooled. A thermosetting polymer, once heated and set, becomes permanently hard and cannot be reshaped. For example, polyethylene is thermosoftening, while epoxy resin is thermosetting.
Explanation
The answer demonstrates understanding of the key behavioural difference on heating and provides correct examples, testing recall and application of the definition.
Common mistake
Confusing Polymer Types
Students often confuse thermosoftening polymers with thermosetting polymers, thinking both behave the same way when heated.
Remember that thermosoftening polymers can be reshaped when heated, while thermosetting polymers do not change shape and become rigid upon heating.
