Which is true about Buna- N ?

Options

  1. AIt is a linear polymer of 1 , 3 -butadiene.
  2. BIt is obtained by copolymerization of 1 , 3 -butadiene and styrene.
  3. CIt is obtained by copolymerization of 1 , 3 -butadiene and acrylonitrile.
  4. DThe suffix N in Buna- N stands for its natural occurrence.

Correct answer

C. It is obtained by copolymerization of 1 , 3 -butadiene and acrylonitrile.

Step-by-step solution

Buna- N is formed by the co-polymerization of 1,3-butadiene and vinylcyanide(acrylonitrile) in the presence of a peroxide catalyst. It is a synthetic rubber.
