Which statement regarding polymers is not correct?
Which statement regarding polymers is not correct?
Options
- AFibers possess high tensile strength.
- BThermoplastic polymers are capable of repeatedly softening and hardening on heating and cooling respectively.
- CThermosetting polymers are reusable.
- DElastomers have polymer chains held together by weak intermolecular forces.
Correct answer
C. Thermosetting polymers are reusable.
Step-by-step solution
A thermosetting polymer, often called a thermoset, is a polymer that is obtained by irreversibly hardening a soft solid or viscous liquid prepolymer.
They can't be reused.
Thermoplastic polymers are capable of repeatedly softening and hardening on heating and cooling respectively.They can be re-used.
Fibres have high tensile strength.
Elastomers have polymer chains held together by weak intermolecular forces, they have high elasticity.
Hence, option C is the correct answer.
