Chemistry - Polymer Question with Solution | TestHub

Thermoplastic polymers are linear or slightly branched long chain molecules capable of repeatedly softening on heating and hardening on cooling.

The intermolecular forces of attraction in thermoplastic polymers are intermediate between those of elastomers and fibres.

Because they soften on heating, they can be easily moulded into desired shapes.

Extensive cross-linking by covalent bonds is a characteristic of thermosetting polymers, not thermoplastic polymers. Therefore, the statement about extensive cross-linking is incorrect.

Answer: These possess extensive cross linking by covalent bonds.
