Q149 / 200 · MHT CET - Medical 2026 (24 April Shift 1) · Chemistry
Which one of the following polymers is NOT obtained by condensation polymerisation?
- ANylon 6,6
- Correct answerBBuna-N
- CBakelite
- DTerylene
Solution
Buna-N is an addition polymer formed by the copolymerisation of $1,3$-butadiene and acrylonitrile.
Nylon $6,6$ is a condensation polymer of hexamethylenediamine and adipic acid.
Bakelite is a condensation polymer of phenol and formaldehyde.
Terylene is a condensation polymer of ethylene glycol and terephthalic acid.
Answer: Buna-N
Nylon $6,6$ is a condensation polymer of hexamethylenediamine and adipic acid.
Bakelite is a condensation polymer of phenol and formaldehyde.
Terylene is a condensation polymer of ethylene glycol and terephthalic acid.
Answer: Buna-N
Hence, the correct answer is option: 'B'.
