|
Students should be able to, given appropriate information explain how the properties of materials are related to their uses and select appropriate materials. |
|
What is a polymer? |
|
|
|
The properties of polymers depend on what monomers they are made from and the conditions under which they are made. For example, low density (LD) and high density (HD) poly(ethene) are produced from ethene. |
|
What factors determine the type of polymers that are made? Observe everyday examples of LH and HD polymers to deduce their properties and structure |
|
|
|
Thermosoftening polymers melt when they are heated. Thermosetting polymers do not melt when they are heated. |
|
What is the difference between thermo softening and thermosetting polymers? |
|
|
|
Students should be able to explain how low density and high density poly(ethene) are both produced from ethene. |
|
How are high density and low density poly(ethene) are produced from ethene? |
|
|
|
Students should be able to explain the difference between thermosoftening and thermosetting polymers in terms of their structures. |
|
How are the structures of thermosoftening and thermosetting polymers different? |
