Monomer- a single unit of a polymer
polymer- is made of many monomers
ethene--> polyethene
propane---> polypropene
styrene---> polystyrene
monomers must have a double bond to become a polymer
polythene E.g- plastic bags
Unlimited prat of polythene chain
Addition polymerization- this is when a polymer is turned into a polymer
Propene into Polypropene
Styrene to Polystyrene
