Question

Draw structures of the step-growth polymers you would expect to obtain from the following reactions:

Short answer

a.

b.

c.

Step-by-step solution

Polymer formed in (a)

Formation of Polyether takes place by the removal of halogen from one reactant and halogen from another reactant.

Formation of polyether

Polyester is formed in (b)

By the addition of acid removal of water takes place, by removal of –OH from alcohol and hydrogen from carboxylic acid and then polymerisation takes place. Then it leads to the formation of polyester.

Formation of polyester

 Step 3: Polyamide is formed in (c)

In the formation of amide takes place by the removal of hydrogen from amine and removal of chlorine from another reactant. After this polymerisation takes place.

Formation of polyamide
