Plastics

 

Here we will break down what makes up your Tupperware, clothes and water bottles: Plastics.

Plastics are polymers. Polymers are molecules that have very long chains of repeating units called monomers.

Naming Polymers

You need to be able to name monomers, polymers and repeating units.

For the molecule polyethanol:

Structure A is the monomer.

Structure B is the repeating unit.

Structure C is the polymer.

Addition Polymerisation

Addition polymerisation occurs when addition reactions occur between monomers to create a polymer.

Starches, proteins and DNA are examples of natural polymers as they are molecules of repeating units.
