5.2 Making Polymers from Alkenes Flashcards
1
Q
What are plastics made from?
A
Very large molecules called polymers
2
Q
What are polymers made from?
A
Small molecules called monomers joined together
3
Q
What is the reaction called to make a polymer?
A
Polymerisation
4
Q
How is poly(ethene) made?
A
By lots of ethene molecules joined together
5
Q
What happens in a polymerisation reaction?
A
The double bond in each alkene molecule becomes a single bond and thousands of alkene molecules join together in long chains
6
Q
What can propene form?
A
Polypropene
7
Q
Why can we make polymers from alkenes but not alkanes?
A
Because alkanes do not have a double bond
