Polymerisation Reactions Flashcards
Give an example of an addition reaction
The addition of bromine to ethane
Do addition reactions only occur between a molecule and an unsaturated compound?
No
It is possible for molecules containing double bonds to undergo addition reacting among themselves
Give an example of an addition reaction between two unsaturated molecules
It is possible for molecules of ethene to link with each other to form long chains of carbon atoms
What is formed when molecules of ethene link together during an addition reaction?
A long chain of carbon atoms
What is the name of the long chain of carbon atoms formed during the addition reaction of ethene and ethene?
Poly(ethene)
What is poly(ethene) more commonly called
Polythene
Polythene is an example of what?
A polymer
Give an example of a polymer
Polythene
Define polymers
Polymers are long chain molecules made by joining together many small molecules
What do polymers consist of?
Repeating structures
What are the small molecules which makes up polymers called?
Monomers
What is a monomer?
The small molecules from which a polymer is made
What is the monomer used to manufacture the polymer polythene?
Ethene
What is ethene the monomer of?
Polythene
What are polymers commonly called?
Plastics
Other than polythene, give an example of another polymer.
Poly(chloroethene)
What is polythene also called?
Polyvinyl chloride or PVC
How is polychloroethene made?
It is made by reacting together chloroethene molecules
What is chloroethene also called?
Monochloroethene
What is made by the polymerisation of propene?
Poly(propene)
What makes poly(propene) through polymerisation?
Propene
What can poly(propene) be used for?
2
To make a fibre that is used in the manufacture of rules (does not rot - different colours)
Toys, jugs, beakers etc
Define a repeating unit of a polymer
The repeating unit of a polymer is that part of the polymer whose repetition produces the complete polymer chain except for the end group
Why are polymers such as polythene and poly(propene) categorized as addition polymers?
Because their manufacture involves addition reactions
