improve-tution3

 

1. How is a polymer created? What is this process called?

2. Why do all polymers not have the same properties?

3. What characteristic allows monomers to join together?

4. Is it an advantage or a disadvantage that polymers are chemically unreactive?

1.
A polymer is created by joining together lot of small molecules called monomers. This process is called polymerisation.

2.
The properties depend on the different monomers.

3.
Monomers have a double bond which ‘opens up’.

4.
Advantage because it will last a long time without becoming damaged
Disadvantage because it will not decompose so it is hard to dispose of /causing a littering problem.
