Explain the diffe

Buna-N:

The monomers are as follows:

Butadiene- CH₂ = CH-CH = CHs

Acrylonitrile- CH2 = CH - CN

The reaction is as follows:

This polymer is also called as nitrile rubber and this used in the manufacture of oil seals, protective gloves etc.

Buna – S:

The monomers are as follows:

1, 3- Butadiene

Styrene

The reaction as follows:

It is also called as Styrene Butadiene Rubber and it possess less tensile strength in comparison with natural rubber and it is used in the manufacture of automobile tyres etc.
