Interpretation:
Identify the structural class of the following polymer and also the monomer units used to make it.
Concept introduction:
In this reaction, the polymeric product formed is a polycarbonate. Polycarbonates are the compounds which are somewhat same as polyesters but contain two (-OR) groups.
(i)
These polymers are similar in structure to a long straight chain with identical links connected to each other. The monomers in these are linked together to form a long chain. These polymers have high melting points and are of higher density.
Example of this is PVC (Poly-vinyl chloride). This polymer is largely used for making electric cables and pipes.
(ii)
The structure of these polymers is like branches originating at random points from a single linear chain. Monomers join together to form a long straight chain with some branched chains of different lengths.
As a result of these branches, the polymers are not closely packed together. They are of low density having low melting points. Low-density polyethene (LDPE) used in plastic bags and general purpose containers are the common examples.
(iii)
In this type of polymers, monomers are linked together to form a 3D network. These monomers are bi-functional and tri-functional in nature. These polymers are brittle and hard.
Some of the examples are: Bakelite, melamine etc.

- Using what we have learned in CHEM 2310 and up through class on 1/31, propose a series of reaction steps to achieve the transformation below. Be sure to show all reagents and intermediates for full credit. You do not need to draw mechanism arrows, but you do need to include charges where appropriate. If you do not put your group name, you will get half credit at most. ?
