Which from following polymer is obtained by addition polymerization?

  • Correct answer
    A
    Figure
  • B
    $[\text{NH} - (\text{CH}_2)_5 - \text{CO}]_n$
  • C
    Figure
  • D
    Figure

Solution

Addition polymerization involves the repeated addition of monomer molecules possessing double or triple bonds to form a polymer, without the elimination of any small molecules.

Option (322647) represents Polyacrylonitrile (PAN), which is formed by the addition polymerization of acrylonitrile ($\text{CH}_2=\text{CH}-\text{CN}$).

Option (322648) represents Nylon-6, which is a condensation polymer of caprolactam.

Option (322649) represents Terylene (Dacron), which is a condensation polymer of ethylene glycol and terephthalic acid.

Option (322650) represents PHBV, which is a condensation polymer of 3-hydroxybutanoic acid and 3-hydroxypentanoic acid.

Therefore, the polymer obtained by addition polymerization is Polyacrylonitrile.

Answer: Figure

Hence, the correct answer is option: 'A'.
