Plastics and Synthetic Fibres Learning outcomes for Topic 8
Plastics and Synthetic Fibres What are most plastics and synthetic fibres made from? What is meant by the word synthetic in this context? What does biodegradable mean?
Synthetic Fibres What are the advantages and disadvantages of synthetic fibres?
Plastics What are the properties of plastics? How do the properties of plastics relate to their uses? What are the problems with plastics? What happens to plastic when it burns? How how does burning help us to see what elements are present in the original plastic?
Thermosetting Plastics What is a thermosetting plastic? What is a thermoplastic? What are thermosetting plastics used for?
Polymerisation 1 What is a monomer? What is a polymer? What is polymerisation? Give an example of a polymer.
Polymerisation 2 How are plastics made? How do monomers join together to make a polymer? What is addition polymerisation? Give an example of addition polymerisation.
