- 1What are polymers?Most important man made material.
- 2What is polymerisation?Loads of small molecules linking together.
- 3How are plastics formed?When monomers (small molecules) link together to make a polymer (long molecule)
- 4What is the main chemical in this process?Carbon.
- 5How do these molecules polymerise?Under high pressure they join to make long chains called polymers.
- 6What does the type of monomer change in the polymers?It creates different physical features of polymers. Some are
- 7What are milk bottles made of, why is it this material?High-density Polythene.
Which is strong and rigid. - 8What are the properties of low-density polymers?They have a low boiling point. They are usually
- 9How do plastic kettles work? Give me an example of what type of plastic could be used.They are heat-resistant.
Example: Polypropene. - 10What have polymers replaced?Natural Materials.
- 11Why are polymers used over natural materials?They are generally lighter, more durable, water-resistant and cheaper.
