Thermosetting resins are those polymers, which__________________?
Correct answer: A. Do not increase in plasticity with rise in temperature
- A. Do not increase in plasticity with rise in temperature
- B. Allow slip to occur between molecules
- C. Do not take on a permanent set
- D. None of these
Explanation
Thermosetting polymers form permanent cross-links during curing, so they do not soften and flow again when reheated. This distinguishes them from thermoplastics, which become more plastic with increasing temperature.
