Question

Show the structure of the polymer that results from heating the following diepoxide and diamine:

Short answer

When the diepoxide monomer is reacted with the diamine then the highly strained epoxide ring is open by SN₂ mechanism.

In the given reaction lone pair of nitrogen attack the epoxide ring and we get the polymer as shown below;

Step-by-step solution

Reaction of diepoxide and diamine

When the diepoxide monomer is reacted with the diamine then the highly strained epoxide ring is open by SN₂ mechanism.
