Question

What are elastomers?... Class 11 physics​

Answer 1

Answer:

Elastomer

An elastomer is a polymer with viscoelasticity (i.e., both viscosity and elasticity) and has very weak intermolecular forces, generally low Young's modulus and high failure strain compared with other materials. ... IUPAC defines the term "elastomer" by "Polymer that displays rubber-like elasticity."

Answer 2

Answer: It is explained as follows:

Explanation:

Elastomers are polymers which have viscoelasticity i.e. they exhibit both viscosity and elasticity.

The weak intermolecular forces that hold the molecules of elastomers together cause them to typically have low Young's modulus, high yield strength, or high failure strain.

They acquire the special ability to regain their original size and shape after being significantly stretched due to proper distribution of applied pressure.

Different examples of Elastomers include natural rubber, polyurethanes, polybutadiene, silicone and neoprene etc.
