Text Solution

AI Generated Solution

To determine the monomers of SBR (Styrene-Butadiene Rubber) or Buna-S, we can follow these steps: ### Step 1: Understand the Components - SBR is a copolymer made from two different monomers. - The two monomers involved in the formation of SBR are styrene and butadiene. ### Step 2: Identify the Monomers - **Styrene**: This is an aromatic compound with the formula C₈H₈. It is derived from benzene and has a vinyl group (C=C). ...

What is the common monomer for buna-S and buna-N rubber ?

Rubber is a naturally occurring polymer, which is a linear polymer of isoprene. It can be easily deformed but regains its original shape after the stress is relieved. The properties of natural rubber can be modified and improved by process of vulcanization. It is mixed with 3 to 5% sulphur and heated at 373-423 K. This forms cross links through disulphide bonds (-S-S-) , which make rubber hard, tough with greater tensile strength. There are many different formulations of synthetic rubbers. These are copolymers in which one of the monomer is isoprene. Some common examples are neoprene rubber, Buna-S, Buna-N, etc. Name the monomers of synthetic rubber Buna-S.

Buna - S is a
