Question

Formations of nylons and polyesters are called step monomer units ?

• A. The polymerizations are formed by adding a monomer step by step
• B. The polymers are formed by condensations and monomers are joined by loss of simple molecules like water
• C. The monomers used for condensations are unsaturated molecules
• D. The polymers are formed by additions of a large number of free radicals formed by monomers.

Answer 1

Answer: (B)

The polymers are formed by condensations and monomers are joined by loss of simple molecules like water

Answer 2

Step growth polymers are condensations polymers. They are formed by the loss of simple molecules like water, alcohol. Etc. and lead to the formations of high molecular mass condensations polymers.
