Sturcture of Polymers

4 important questions on Sturcture of Polymers

What is the difference between a repeat unit and a monomer?

A monomer is the small molecule of which the polymer is synthesized. A repeat unit is a structural entity which is repeated along the chain.

Where m is the molecular weigt of the repeat unit.

What are crosslinked polymers?

When adjecent polymer chains are interconnected at various points by covalent bonds, the polymer is called crosslinked.
