Which of the following is a cross-linked, thermosetting polymer?
Options:
Answer:
A
Solution:
Bakelite is formed by the condensation reaction of phenol with formaldehyde. It is a highly cross-linked, thermosetting polymer which, once molded, cannot be remolded or reshaped by heating.
PVC, Polystyrene, and PTFE (Teflon) are examples of thermoplastic polymers, which can be repeatedly softened by heating and hardened by cooling.
