Answer:

Buna-S rubber is one of the commonly used synthetic rubber.

Explanation:

It is a random co-polymer formed by the emulsion polymerisation of a mixture of 1:3 butadiene and styrene in the presence of peroxide catalyst at 5 degree Celsius and therefore the product is called as cold rubber. The rubber obtained is also called Styrene butadiene rubber (SBR).

In Buna-S, Bu stands for butadiene and, Na for sodium and S for styrene.
