  • Products from oil
    • Making polymers from alkenes
      • Polymers are plastics
      • smaller polymers are called monomers
      • Reaction is called polymerisation
      •  
    • New and useful polymers
      • Dentil fillings: replace fillings that contain mercury
      • plasters: light sensitive polymers
      • Hydrogels: trap water
      • Shape memory polymers: original shape when temperature or other conditions change
    • Plastic waste
      • most polymers are not biodegradable
        • Cause unpleasent sights
      • biogradable plastics are decomposed by the action of microorganism in soil
      • Making plastic with sarch granules in their structure helps the microorganism break down a plastic
      • We can make biodegradable plastics from plant material such as cornsarch
    • Ethanol
      • Fermenting sugar using enzymes in yeast
      • Made by hydration of ethene with steam in a catalyst
  • Cracking Hydrocarbons

        • Made by hydration of ethene with steam in a catalyst
    • Cracking
      • 1) heating the mixture of hydrocarbon vapours and steam to a very high temp.
      • 2) passing hyrdrocarbons vapours ovver a hot catalyst
    • Some smaller molecules are alkanes, which are saturated hydrocarbons
      • Formula : C  H
    • Large hydrocarbons can be broke down in a process called cracking
    • Alkenes have a double bond
      • turn colourless when reacted with bromine water
