Question:
Identify polyamide polymer from following.
Identify polyamide polymer from following.
Show Hint
A polyamide has repeating amide (-CONH-) links in its chain. Think of which listed polymer is a type of nylon.
Updated On: Nov 13, 2026
- SBR
- Melamine formaldehyde polymer
- Bakelite
- Nylon 6,6
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept
Polyamides are polymers whose monomer units are joined by amide linkages, \(-\text{CONH}-\).
Step 2: Check the polymers
SBR is a copolymer of styrene and butadiene (a rubber).
Melamine formaldehyde polymer and Bakelite are condensation (thermosetting) resins with no amide links.
Nylon 6,6 is made from hexamethylenediamine and adipic acid and contains amide links.
Step 3: Match
Nylon 6,6 is the polyamide.
Final Answer:
Nylon 6,6 is the polyamide polymer. \[ \boxed{\text{(D) }\text{Nylon 6,6}} \]
