3.2 Plastics Flashcards
1
Q
What is a ploymer?
A
A long chain molecule created by adding together multiple identical monomers
2
Q
What is the process of reacting monomers together to form a polymer called?
A
Addition polymerisation
3
Q
What characteristic makes hydrocarbons able to undergo an addition reaction?
A
Carbon-carbon double bond (C=C)
4
Q
What properties must the monomers for addition polymerisation have?
A
They must be unsaturated
5
Q
How should polymers be drawn?
A
With an open carbon bond at each end to show that this is a snapshot of a much longer chain
6
Q
What is a repeating unit?
A
The shortest section of the polymer chain which, if repeated, would give the complete polymer chain (bar the end groups)
7
Q
What is the only naturally occurring addition polymer?
A
Rubber
