4h. Synthetic polymers

Question 1

4.44 How is an addition polymer formed

Answer 1

By the joining up of many small molecules called monomers

Question 2

4.44 What is the process of the linking up of many monomers called

Answer 2

addition polymerisation

Question 3

4.44 What kind of unit is each monomer in the linking up process

Answer 3

a repeat unit

Question 4

4.44 What do polymerisation reactions usually require

Answer 4

High pressure and the use of a catalyst

Question 5

4.45 How are Addition polymers formed

Answer 5

By the joining up of many monomers and only occurs in monomers that contain C=C bonds

Question 6

4.45 Explain the addition process

Answer 6

One of the bonds in each C=C bond breaks and forms a bond with the adjacent monomer with the polymer being formed containing single bonds only
