Question

$Nylon-6,6$ is an example of a polymer formed by

• A. chain growth polymerization
• B. crossed linked polymerization
• C. addition polymerization
• D. step growth polymerization

Answer 1

Answer: (D)

step growth polymerization

Answer 2

Nylon-6,6 is an example of step growth polymerization as monomers adipic acid and 'hexamethylenediamine are bifunctional and form bond with the loss of simple molecules. The dimer formed also contains two functional groups, thus undergoes a series of condensations in a stepwise manner.
