Which of the following is produced by condensation polymerisation ?
Correct answer: B. Bakelite
- A. Polythene
- B. Bakelite
- C. Poly vinyl chloride
- D. Polystyrene
Explanation
Bakelite is formed by condensation of phenol and formaldehyde, with water released as a by-product during network formation. Polythene, PVC, and polystyrene are addition polymers formed without such small-molecule elimination.
