Question

_________materials are those materials that are made of polymers that are joined by chemical bonds, acquiring a slightly cross linked structure.

• A. Thermoplastic
• B. Elastomer
• C. Thermoset
• D. Polyethylene

Hint:

Elastomers are flexible, slightly cross-linked polymers that can stretch and return to their original shape.

Answer 1

The Correct Option is B

Elastomers are a class of polymer materials characterized by their elastic properties. They have polymers joined by chemical bonds with a slightly cross-linked structure, which gives them the ability to stretch and return to their original shape.
Key features of elastomers include:

Flexibility and elasticity
Ability to withstand deformation and recover
Used in products like rubber bands, tires, and seals

Explanation of Other Options:

(A) Thermoplastic: Polymers that soften when heated and harden when cooled, without cross-linking.
(C) Thermoset: Polymers with extensive cross-linking that harden permanently after heating.
(D) Polyethylene: A type of thermoplastic polymer, not specifically elastomeric.
Hence, the correct answer is option (B).
