Chapter 31: 23E (page 1054)

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

Short Answer

Expert verified

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;
