Addition polymers + polymerisation

Question 1

What is polymerisation?

Answer 1

long molecules formed when multiple monomers join together

Question 2

What does polymerisation need, besides the monomers?

Answer 2

High pressure and a catalyst

Question 3

What is the usual monomer of. plastic

Answer 3

Alkenes

Question 4

Addition polymers are made from what?

Answer 4

Unsaturated monomers

Question 5

How does polymerisation work?

Answer 5

lots of unsaturated alkenes can open their double bond and join together to form a polymer chain. This is called addition polymerisation

Question 6

What would be the name of the polymer if lots of ethene molecules joined together?

Answer 6

Poly-ethene

Question 7

How do you draw the repeating unit of a polymer?

Answer 7

1. draw the two alkene carbons and replace the double bond with a single bond
2. add an extra single bond to each of the carbons on either side
3. fill the rest of the groups in the same way as they were arranged around the double bond
4. add brackets and put an ‘n’ after it to show there are lots of them
