C4-1 Addition polymers

Polymers are formed by chemically joining many small molecules called monomers together. There are two types of polymerisation. What type of polymerisation involves alkenes as monomers?

Polystyrene is is shown in the diagram. What monomer makes the polymer polystyrene?

Many plastics are polymers. Polymers are long molecules formed when lots of monomers join together.

Which TWO conditions are usually required for polymerisation to occur?

• High temperature

• High Pressure

• High surface tension

• Catalyst
