The monomers of buna-S rubber are
- A vinyl chloride and sulphur
- B butadiene
- C styrene and butadiene
- D isoprene and butadiene
Answer & Solution
Correct Answer
(C) styrene and butadiene
Step-by-step Solution
Detailed explanation
Buna-S rubber is also called SBR styrene -butadiene rubber. It is a copolymer of \(75 \%\) butadiene \(\left(\mathrm{CH}_{2}=\mathrm{CH}-\mathrm{CH}=\mathrm{CH}_{2}\right)\) and \(25 \%\) styrene \(\left(\mathrm{C}_{6} \mathrm{H}_{5}-\mathrm{CH}=\mathrm{CH}_{2}\right)\).
