Answer:
The correct answer is (A) Bakelite.
Explanation:
Bakelite is defined as a condensation polymer of formaldehyde and phenol. It is a poor heat conductor and is used to make electrical switches and handles .
Rest all our polymers but are not crosslinked in nature.
- Polyester is formed by benzene−1,4−dicarboxylic acid and ethane−1,2−diol condensation.
- PVC is formed by the polymerisation of Vinyl chloride.
- Nylon is prepared by polymerization of Caprolactam.
