Question

What is an elastomer?

• A. Elastomers are hard, brittle polymers with cross-links
• B. Elastomers are rubber-like solids with weak intermolecular forces.
• C. Elastomers are stretchable solids with strong intermolecular forces.
• D. Elastomers are hard, brittle solids with strong intermolecular forces

Answer 1

The correct option is B Elastomers are rubber-like solids with weak intermolecular forces.

Elastomers are rubber-like solids with weak intermolecular forces. They stretch when under stress and return back to their initial configuration when the stress is removed. They have cross-links between their polymer chains which allows them to exhibit these properties.
