Nitrile rubber is produced by the polymerisation of_________________?
Correct answer: D. Acrylonitrile & butadiene
- A. None of these
- B. Acrylonitrile & styrene
- C. Isobutylene & isoprene
- D. Acrylonitrile & butadiene
Explanation
Nitrile rubber is formed by copolymerising acrylonitrile with 1,3-butadiene. The nitrile groups provide oil resistance, while the butadiene units give rubbery elasticity.
