Question:
Which of the following polymers is not an example of addition polymerization?
Which of the following polymers is not an example of addition polymerization?
Show Hint
Bakelite forms by condensation of phenol and formaldehyde with loss of water.
Updated On: Nov 12, 2026
- PVC
- Bakelite
- Polyethylene
- Teflon
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept
Addition polymers form by joining alkene monomers through C=C bonds without losing any small molecule.
Condensation polymers form with loss of small molecules like water.
Step 2: Check the polymers
PVC is from vinyl chloride, polyethylene is from ethene, and Teflon is from tetrafluoroethene. All are addition polymers.
Bakelite is made from phenol and formaldehyde with elimination of water.
Step 3: Conclusion
Bakelite is a condensation polymer, so it is not an addition polymer.
Final Answer:
Bakelite is not an addition polymer, option (B). \[ \boxed{\text{(B) }\text{Bakelite}} \]
