Question

Which is true about Buna-N?

• A. It is a linear polymer of 1, 3-butadiene
• B. It is obtained by copolymerization of 1, 3-butadiene and styrene
• C. It is obtained by copolymerization of 1, 3-butadiene and acrylonitrile
• D. The suffix N in Buna-N stands for its natural occurrence.

Answer 1

Answer: (C)

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

Answer 2

$Buna-N$ is formed by copolymerisation of $1-3$-$butadiene$ and $acrylonitrile$

$Hence,$ the correct option is (C): It is obtained by copolymerization of 1, 3$$-butadiene and $acrylonitrile$
