what do you mean by Elastomers ? explain briefly
Answers
Answer:
An elastomer is a polymer with viscoelasticity (i.e both elasticity ) and with 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:
The polymer chains are held Together by the weakest intermolecular forces. Elastomers become soft on heating and can be moulded into any desired shape.
The weak intermolecular forces permit the polymer to be stretched by the application of small force. A new crosslinks may be introduced in between the change the chains.
These cross- links between the change of the elastomer help it to be come back to its original position after the force is removed.
