Question

Q.7.Which materials are called elastomers​

Answer 1

Answer:

hey here is your answer

Rubber-like solids with elastic properties are called elastomers. Polymer chains are held together in these materials by relatively weak intermolecular bonds, which permit the polymers to stretch in response to macroscopic stresses. Natural rubber, neoprene rubber, buna-s and buna-n are all examples of such elastomers

hope it help you ☺️

Answer 2

Answer:

Elastomers are polymers that are having viscosity as well as elasticity and therefore are known as viscoelasticity. The molecules of elastomers held together by weak inter-molecular forces, generally they exhibit low Young's modulus and high yield strength or high failure strain.
