1 Chemicals from Oil Chemicals from Oil PLASTICS

2 Plastics When oil is cracked ethene is often made. Ethene is a very useful molecule as it is the starting material for making many plastics.

3 Plastics Plastics are huge molecules. They are usually made from chains of thousands of atoms. These long chains are called polymers

4 Plastics Polymers are made from joining thousands of small molecules called monomers together.

5 Plastics Ethene is a monomer that joins up to form poly(ethene). This reaction is called polymerisation

6 Plastics Different plastics can be made from different monomers.

7 Uses of Different Plastics Polyethene Plastic bags “Rubber” ducks Washing up bowl Plastic dustbins

8 Uses of Different Plastics Poly(styrene) Drink containers Packaging Ceiling tiles Yoghurt pots

9 Uses of Different Plastics Poly(vinyl chloride) PVC Vinyl records Drainpipes Window frames Plastic rain coat

10 Uses of Different Plastics Poly(propene) Crates Fishing nets

11 Uses of Different Plastics Nylon Toothbrush Sports wear tights

12 MonomerPolymer ethenepoly(ethene) styrenepoly(styrene) vinyl chloridepoly(vinyl chloride) PVC
