• Addition polymerisation

  The process in which unsaturated alkene molecules (monomers) add on to a growing polymer chain one at a time to form a very long saturated molecular chain (the addition polymer).
• Condensation polymerisation


  Chemical reaction in which monomer join together to form a polymer and a water molecule
• Three examples of biological polymers

  DNA made from nucleotides

  Proteins made from amino acids

  Starch and Cellulose made from Glucose
• Difference between starch and cellulose

  Starch is branched but cellulose is straight chain
• How a polyester forms

  Polymerisation of dicarboxylic acid and diol
