Thermosetting resins/polymers as compared to thermoplastic ones are ____________________?
Correct answer: C. More brittle
- A. Soluble in all organic solvents
- B. Formed by addition polymerisation only
- C. More brittle
- D. Easily reshaped & reused
Explanation
Thermosetting polymers form a permanent three-dimensional cross-linked network during curing, so they cannot be melted and reshaped like thermoplastics. This rigid network generally makes them harder but more brittle.
