Question

Which of the following are thermoplastic polymers?

• A. Polythene, urea-formaldehyde, polyvinyls
• B. Bakelite, polythene, polystyrene
• C. Polythene, polystyrene, polyvinyls
• D. Urea-formaldehyde, polystyrene, bakelite

Answer 1

Answer: (C)

Polythene, polystyrene, polyvinyls

Polythene, polystyrene, polyvinyls are the thermoplastic polymers,

Characteristics of thermoplastic polymers-

• These are linear and slightly branched long chain molecules,
• These are capable of repeatedly softening on heating and hardening on cooling,
• These possess intermolecular forces of attraction intermediate between elastomers and fibers.

The correct option is [C].
