Rubber-like solids with elastic properties are called

Options

A. elastomers
B. fibers
C. thermosetting polymers
D. thermoplastic polymers

Answer

**Solution:**

Rubber-like solids with elastic properties are classified as **elastomers**.

1. **Definition of Polymers**: Polymers are large molecules made up of repeating units called monomers. They can have various properties based on their structure and the forces acting between the molecules.

2. **Classification of Polymers**: Polymers can be classified based on the types of intermolecular forces present between their chains.

3. **Elastomers**: Among the classifications, elastomers are specifically the type of polymers that exhibit rubber-like properties. They can be stretched significantly and return to their original shape when the force is released.

4. **Intermolecular Forces**: The intermolecular forces in elastomers are primarily Van der Waals forces, which are relatively weak. This weakness allows the chains to move past each other, enabling the material to stretch and then recover.

5. **Properties of Elastomers**: The key characteristics of elastomers include their ability to undergo deformation and return to their original form, making them ideal for applications that require flexibility and resilience.

**Final Answer**: Rubber-like solids with elastic properties are called **elastomers**.
