Chemistry - Polymer Question with Solution | TestHub

Elastomers are rubber-like solid polymers with elastic properties, where the polymer chains are held together by the weakest intermolecular forces.

Buna-S is a synthetic rubber and is classified as an elastomer.

Nylon 6,6 and Terylene are classified as fibres, which have strong intermolecular forces like hydrogen bonding.

Polythene is a thermoplastic polymer, which has intermolecular forces intermediate between elastomers and fibres.

Answer: Buna-S
