- 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
- most polymers are not biodegradable
- Ethanol
- Fermenting sugar using enzymes in yeast
- Made by hydration of ethene with steam in a catalyst
- Making polymers from alkenes
- Cracking Hydrocarbons

- Made by hydration of ethene with steam in a catalyst
- Making polymers from alkenes
- 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
