Monochloroethene

20
Q

What is made by the polymerisation of propene?

A

Poly(propene)

21
Q

What makes poly(propene) through polymerisation?

A

Propene

22
Q

What can poly(propene) be used for?

2

A

To make a fibre that is used in the manufacture of rules (does not rot - different colours)

Toys, jugs, beakers etc

23
Q

Define a repeating unit of a polymer

A

The repeating unit of a polymer is that part of the polymer whose repetition produces the complete polymer chain except for the end group

24
Q

Why are polymers such as polythene and poly(propene) categorized as addition polymers?

A

Because their manufacture involves addition reactions
