Hint: Terylene fibre is a synthetic polymer. It is produced by a condensation reaction mechanism between ethylene glycol and terephthalic acid. It is a poly ester. Buna-S rubber is produced by the reaction between styrene and butadiene by addition reaction mechanism.

Complete step by step solution:
The difference between terylene fibre and Buna -S- rubber (elastomers) as follow:
- Terylene fibre is a poly ester. On the other hand, Buna -S- rubber (elastomers) is a polymer conjugated system of double bond.
- The monomers of terylene are ethylene glycol and terephthalic acid. On the other hand, the monomers of Buna-S rubber are styrene and butadiene.
- Terylene is a fibre like polymer. But Buna -S- rubber is an elastomer. Elastomers are basically one kind of polymer having elasticity.
- The binding forces are very strong in terylene. But in case of Buna -S- rubber the binding force is weak.
- Terylene is formed by a condensation mechanism. It is also called condensation polymer. But Buna -S- rubber is an additional polymer. It is also called an additional polymer.
- The use of terylene is used as a fabric called polyester tricot. On the other hand, Buna -S- rubber is used in coating papers, in shoe heels, chewing gums etc.

Note: synthetic polymers are basically those polymers which can be made in the laboratory. Those polymers are also called man-made polymers. Some examples of synthetic polymers are, nylon, Teflon, polyethylene, etc.
