They contain covalent bonds between various linear polymer chainsD. They contain strong covalent bonds in their polymer chains
Answer» Correct Answer - D Cross-linked or network polymers are formed from bi-functional and tri-functional monomers and contain strong covalent bonds between various linear polymer chains. These are hard, rigid and brittle due to cross-links e.g. bakelite, melamine etc. Thus, option (d) is incorrect.
