What are polymers?
Long chained molecules.
1 of 10
Polymers are formed when...
Lots of small molecules called MONOMERS join together (polymerisation)
2 of 10
Give an example of a polymer...
Plastics (usually carbon based and their monomers are often ALKENES.)
3 of 10
The monomers that make up addition polymers have a...
Double covalent bond.
4 of 10
Molecules with at least one double covalent bond between carbon atoms are called...
Unsaturated compounds.
5 of 10
Lots of unsaturated monomer molecules (alkenes) can open up their double bonds and join together to form...
polymer chains (process called addition polymerisation)
6 of 10
What determines the properties of plastics?
Forces between molecules.
7 of 10
If the plastic is made up of long chains held together by weak intermolecular forces, then the chains will be free to slide over each other. What does this mean?
Plastic can be stretched easily & have a low melting point.
8 of 10
Some plastics have stronger bonds between the polymer chains - these might be covalent bonds between the chains. What does this mean?
Plastic have higher melting points, rigid, can't be stretched.
