What are polymers used for?
Plastic bottles and bags
6 of 18
What are polymers?
Polymers are a long chanine molecules made up of lots of short molecules called monomers
7 of 18
What is a monomer?
They are single sub unit of a poymer
8 of 18
How do polymers form?
(1) alkene molecules join together. (2) the double bond breaks between the carbon atoms in the alkene (3) the alkene is left with a single bond and joins to other monomers making a polymer
