Question:
Which of the following is not a co-polymer?
Which of the following is not a co-polymer?
Show Hint
A co-polymer is made from two or more different monomers. Neoprene is formed from chloroprene only, so it is not a co-polymer.
Updated On: May 7, 2026
- Buna-S rubber
- Neoprene rubber
- Bakelite
- Urea--Formaldehyde
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
A co-polymer is formed by polymerization of two or more different monomers.
Buna-S rubber is a co-polymer of butadiene and styrene.
Bakelite is formed from phenol and formaldehyde.
Urea-formaldehyde resin is formed from urea and formaldehyde.
But neoprene rubber is formed by polymerization of a single monomer called chloroprene.
Since neoprene is formed from only one type of monomer, it is not a co-polymer.
Therefore, the correct answer is:
\[
\text{Neoprene rubber}.
\]
