Question

Regarding cross-linked or network polymers, which of the following statement is incorrect?

• A. Examples are bakelite and melamine.
• B. They are formed from bi- and tri-functional monomers.
• C. They contain covalent bonds between various linear polymer chains.
• D. They contain weak covalents bonds in their polymer chains.

Answer 1

Answer: (D)

Cross linked or network polymers are formed from bifunctional and tri-functional monomers and contain strong covalent bonds between various linear polymer chains, e.g. bakelite, melamine etc, Option D is not related to crosslinking, hence incorrect.
