Question

Which of the following synthetic rubbers is specifically synthesized by the copolymerization of 1,3-butadiene and acrylonitrile, rendering it highly resistant to the swelling action of petrol and lubricating oils?

Prashant Kotian · Accepted Answer

Correct answer: D. Buna-N (Nitrile rubber) uses acrylonitrile as its comonomer. The highly polar cyano () group makes the resulting polymer highly resistant to non-polar solvents like petrol and oils.
