  • Teflon
  • Polyacrolonitrile
  • LDP
  • PHBV
Show Solution

The Correct Option is D

Solution and Explanation

Step 1: Look at the monomers:
Alkene monomers ($\text{CF}_2=\text{CF}_2$, $\text{CH}_2=\text{CHCN}$, $\text{CH}_2=\text{CH}_2$) polymerise by addition.

Step 2: Odd one out:
PHBV monomers are hydroxy acids that join by ester links with loss of water, so it is the condensation polymer.

Final Answer:
The answer is PHBV, option (D). \[ \boxed{\text{PHBV}} \]
