Structural unit

Structural unit

In polymer chemistry, a structural unit is a building block of a polymer chain, and related to the repeat unit. It is the result of a monomer which has been polymerized into a long chain. When different monomer are polymerized, a copolymer is formed. It is a routine way of developing new properties for new materials.


Consider this example: Take polyethylene terephthalate. The monomers which could be used to create this polymer are ethylene glycol and terephthalic acid:


In the polymer, there are two structural units, which are-O-CH2-CH2-O-and-CO-Ph-CO-

The repeat unit is
